Cinema 4D Tutorial: Three Ways to Create Pixel Art

So today we'll use C4DR21's Field Forces to create this diamond dispersion effect with particles moving on the surface! Let's Start MakingIn C4D, first create a new sphere, segmentation can be appropriate to increase a little, type selection for Lcsahedron, Radius value slightly changed a little smaller: !Field Forces to Create Diamond Dispersion Effect 2Add a Disolacer deformer to the sphere, add a noise wave to the shader, and the global scaling of the noise wave can be slightly larger to create this bumpy sphere effect:!Field Forces to Create Diamond Dispersion Effect 3Then add a Subdivision Surface, Subdivision Editor and Subdivision Renderer under Object are set to 1:!Field Forces to Create Diamond Dispersion Effect 4Next is a new feature of C4D R21, we add a Volume Builder to the object. C4D R21's volume generation has added a new mode of vector, it can convert the object directly into a vector, we increase the accuracy of Voxel Size a little bit:!Field Forces to Create Diamond Dispersion Effect 5Next, create a new Random Field and drag it into the volume generation. By default, random fields are created in a cubic space:!Field Forces to Create Diamond Dispersion Effect 6First we can change the creation space to below the object, representing the creation of vectors based on objects:!Field Forces to Create Diamond Dispersion Effect 7But now the direction of the vector is not what we want, because by default it is the direction of the object normal, and for the sake of observation I have slightly enlarged the scale of the random field here:!Field Forces to Create Diamond Dispersion Effect 8Back in Volume Builder, we change the blending mode of the Random Field to Cross, so that the direction of the vector is the direction of the surface to which the object is attached:!Field Forces to Create Diamond Dispersion Effect 9But now the vector is not used, we need to convert it to a field force, so create a new Field Force and drag the volume object into it, selecting the type as Volume Object：!Field Forces to Create Diamond Dispersion Effect 10Now you may not see any effect, you need to create a new Matrix, with Subdivision Surface as the object Object. Distribute it as a surface is fine, then let the matrix generate TP particles, the number can be slightly more:!Field Forces to Create Diamond Dispersion Effect 11By default, the field force does not affect the particles, so you need to do some simple settings. First of all, create a new xpresso tag, and create a new particle transfer in the TP particle creation body: then add a PForce object in the TP dynamic item, which is also a new feature of R21, and then drag the field force into the PForce object, so that the TP particles can be affected by the field force:!Field Forces to Create Diamond Dispersion Effect 12Clicking on play will reveal that the particles will fly out after a period of motion:!Field Forces to Create Diamond Dispersion Effect 13This is because the mode of the field force is not correct, so change the mode of the field force to set the absolute rate, and then increase the intensity a little, you can see the particles hovering along the surface of the object:!Field Forces to Create Diamond Dispersion Effect 14Next we add Thinking Particles to the matrix, change the Limit to From End, then set the Amount to 50, and then play to see the beautiful circling lines:!Field Forces to Create Diamond Dispersion Effect 15!Field Forces to Create Diamond Dispersion Effect 16!Field Forces to Create Diamond Dispersion Effect 17I think the number of particles seems to be a little bit more, so I changed the number of particles to a smaller one:!Field Forces to Create Diamond Dispersion Effect 18When we feel it is almost ready, we can first convert the trace object to an ABC file, make a copy of the subdivision object, and back up the rest and turn it off:!Field Forces to Create Diamond Dispersion Effect 19Now the lines are appearing from nothing, we want it to be the same as the reference case that is always there, so we can offset a little bit in the animation of the ABC file, and then change the frame duration to 180 frames: !Field Forces to Create Diamond Dispersion Effect 20The next step is simple: create a new gem, resize it appropriately, and add a chamfer deformer to it. Create another larger gem, then add a lattice to this gem, with smaller cylinders and spheres. Rotate the angle of the lattice and the sphere, and put them into a group:!Field Forces to Create Diamond Dispersion Effect 21Set the keyframe in the group's rotation , remember to change the curve to linear, and then you can move on to the rendering.Open Redshift, set the render size, first I still use the linear space, and then the scene does not need global lighting, so turn off the GI. Then I did not improve the number of reflections and refraction, because I compared and found that the default parameters seem to look better: create a new HDRI ambient light; you can try more mapping, preferably with the color of this dispersion so the effect will be better:!Field Forces to Create Diamond Dispersion Effect 22Add the RS object label to the sample bar, select the curve mode for the hair on it, and then properly adjust the curve to control the thickness of the beginning and end of the sample bar:!Field Forces to Create Diamond Dispersion Effect 23!Field Forces to Create Diamond Dispersion Effect 24Next is the material, first use a gradient node to connect the material of the sample bar to the color of the luminescence. Change the mode of the gradient node to Alt. I gave the intensity of the glow to 10. Because we are rendering hair, we can give a hair position node to connect to the gradient, so that the hair will have a little gradient according to the position color:!Field Forces to Create Diamond Dispersion Effect 25!Field Forces to Create Diamond Dispersion Effect 26The material of the sphere is nothing special, it is an ordinary dark green reflective material: the next is the material of the jewel body, in fact, is a glass material, I slightly gave it a little reflection of the rough, and then the dispersion I adjusted to 2:!Field Forces to Create Diamond Dispersion Effect 27In the optimization options deselect Weak internal reflections. Then in the lighting details, change whether to affect refraction to always:!Field Forces to Create Diamond Dispersion Effect 28The final lattice material is very simple, is a common luminous material, and then use a gradient color to control the color of the luminous and transparent channel. Sampling settings due to the glass and there is dispersion, my maximum and minimum uniform sampling 256/16, other local samples are 512:!Field Forces to Create Diamond Dispersion Effect 29 The Final ResultFinally, add some glow and see the effect:!Field Forces to Create Diamond Dispersion Effect 30Fox Renderfarm hopes it will be of some help to you.

In scientific research drawings, three-dimensional model diagrams can show more information than two-dimensional plane pictures, especially when designing and preparing nanostructures, three-dimensional model diagrams can intuitively show the design ideas and synthesis paths of materials. For example, in this paper (Ref. Joule 2018; 2: 725-735.), published in Joule magazine, a high-level, high-value, and incisive paper that showcases nano aesthetics, a three-dimensional model is used to intuitively express the synthesis path of the material. Harmonious color scheme and rich details: One of the ingenious features of this group of three-dimensional model diagrams is that irregularly stacked small balls are used to represent the SnO2 layer, which means that SnO2 is stacked by granular nanocrystals.In this article, Fox Renderfarm, the best could rendering services provider and C4D render farm, will share with you a Cinema 4D tutorial about how to make a core-shell structure.

The following is the partial fusion between spheres through volume generation.3.1 Change the sphere type of the cloned subset to tetrahedron, and set the number of segments to 3 (minimum value); create volume generation and volume grids in the generator column, drag the cloned object into the volume generated subset, volume Generated as a subset of the volume grid.!How to Make a Core-shell Structure in Cinema 4D3.2 In the volume generation settings, click Clone to check Use grid points, change the mesh radius to 3 cm, and the voxel size to 1 cm; drag the material of the cloned object to the volume mesh; change the radius of the shadow sphere to 90~95 cm to prevent overlapping of the shadow sphere and the stacked sphere. Finally, render it to the image viewer and save it.!How to Make a Core-shell Structure in Cinema 4D4. If you want to add a layer of spherical shell to the outside, you only need to create a cut spherical shell according to the method in the first step, adjust it to a suitable size, add a subdivision surface, and give it a material. The color of the material can be adjusted by yourself. !How to Make a Core-shell Structure in Cinema 4DThis kind of ball clone filling and rigid body collision method is used to make the stacking effect of the balls. It is suitable for any closed polygon model, but it is necessary to coordinate the relationship between the number and size of the balls and the size of the target polygon. The number of balls is too small. Too much is easy to cause lag. In addition, you can reduce the number of subdivisions of the ball as much as possible without affecting the rendering effect, so as to improve the calculation speed.

The best cloud rendering services provider and C4D render farm, Fox Renderfarm, will share with you a C4D tutorial from 3d artist Flynn. This tutorial uses the C4D R20 version, if using the previous version, you need to adjust some relevant parameters. The tutorial involves a lot of techniques, you can understand and deepen the use of various commands through the case. IdeaThe idea of production will be more important than the learning of operation, so we will talk about the overall thinking process first. Firstly, the first idea was tested. I created a Cube, a Taper effect, and added a Step effect in Falloff. Then use the Cloner to scale to make a rotated column, and then perform a circular radial clone on this basis. AT last, I got a circle, but the circle was not perfect, especially the joint was incomplete, so the method was abandoned.!C4D Tutorial How to Animate a Square CollapseThe second idea is to directly use a disk to operate the surface on the disk, and this method constructs a suitable figure, but the control of the figure is a problem, we can only operate the whole figure but can not operate on a single column, and each part of the axial direction is located in the center, and can not make the feeling of turning.!C4D Tutorial How to Animate a Square CollapseNow there is a problem, in order to better control the animation of the graphics, we need to use the cloned graphics, and directly cloned graphics can not become the desired shape, and directly make the shape can not be very good control, so we need to change the thinking, use cloning to create objects, and then use other methods to make the disk effect. So, using cloning, and then deforming the cloned object, we can achieve the desired effect. ProductionFirstly, to realize the animation control of a column of cells around, so we first make a cell clone object, and directly use the linear mode to create a column of element objects.!C4D Tutorial How to Animate a Square CollapseThen add a Plain to the cloned column element, and adjust the displacement scaling rotation attribute under Parameter. Also add a Field effect in Falloff, and adjust Field/Field to X-. Drag the Linear Field to see the animation effect.!C4D Tutorial How to Animate a Square CollapseIn order to rotate the elements more closely, we also need to adjust the axial position of the basic cube. Select Cube first, then adjust the pivot position in Spline/Axis Center.!C4D Tutorial How to Animate a Square CollapseAfter making the control effect of a unit, we clone it into multiple copies and stack it together evenly.!C4D Tutorial How to Animate a Square CollapseAdd a Spline Wrap and then add a Circle to constrain it to Spline Wrap/Object/Spline. And change Axis to +Z. A new Null is formed by the Spline created and the null made previously.!C4D Tutorial How to Animate a Square CollapseOne thing to note here is that the scope of influence will be changed according to the size of the object at the same level, which will cause the shape to change with the movement of the linear domain. Therefore, we need to check the range box of the deformer to maintain the shape of the shape. When the scope box is fixed and the number of clones is changed, the objects outside the scope box will not be affected by the deformer, and we need to re-fix the scope box.!C4D Tutorial How to Animate a Square CollapseThen we can adjust the size of the disk by changing the size of the disk, and then set the keyframe to the Linear Field. We can get an effect from the outside to the inside.!C4D Tutorial How to Animate a Square CollapseThen the most critical step is that we don't want the motion of each column to be synchronized. At this time, we can use the random effector to achieve this out-of-sync effect. We can use the random effector to make a random offset of the key frame of the motion of each random Linear Field to get the final effect.!C4D Tutorial How to Animate a Square CollapseThe above is all about how to animate a square collapse with C4D.
