With the increasing use of CCSS Catmull-Clark subdivide surface (CCSS), problems have emerged. However, in general, it is better to use CCSS than simply using polyhedron or OpenGL. In the first place, there is no problem with the combination, deformation, skeleton binding, and Paster of the OpenGL, after all, my personal productivity is no longer comparable to that of bluesky's entire R D team, where there are some Ivy League graduates of pH. d. Polyhedron has obvious advantages. It is easy to

The witch is I publish in the Cgtalk work, because originally did not intend to do the tutorial, therefore did not leave the detailed production process, here says probably the production flow, hoped everybody many understanding.
The production of CG illustrations has been a personal hobby, the preference of the Mandarin Duck butterfly aesthetic. At the end of 2008 suddenly wanted to
mappingdisplacement mapping displacement map that we will introduce in the next article. It is different from the previous methods, displacementmapping is a way to change the surface of an object. A technique called micropolygons (micropolygons) Tessellate (MOSAIC) is used to truly change the surface details of an object. The specific process is as follows. First, according to the screen resolution, the visible surface of the model is embedded with a micro-polygon with the same size as the fina
the polygon obtained by the mosaic. Then we can determine the new normal direction for the new polygon. At this point, the surface of the object has indeed added details.
In fact, we can see this technique when using zbrush. When you use zbrush, you will know that the details on the surface will become clearer only when the screen is still. Micro-polygon mosaic plays a similar role. Only the rough surface
. There are two kinds of skin: flexibility and rigidity, different effects and different effects. In general rigid binding can also direct p to bone, parent-child relationship, can also achieve the desired results. (4) Envelope processing: first by adjusting the size of the envelope to adjust the impact of each bone part of the range, note that the inner ring control to half of the outer ring can be. Note that a piece of skin will be affected by several bones, and then adjusted, but also pay att

Therefore, to make the volume of light smaller can improve performance.Light Prepass rendering does not support antialiasing, and can not handle translucent objects, translucent objects will be treated with forward

Clicking each heading in these headings opens a stencil full of shapes. Now, we only use the Basic Shapes stencil.
Click any shape on the Basic Shapes stencil, hold down the mouse button, and drag the shape onto the drawing page.

There are six kinds of inheritance modes in JS, including prototype chain, borrowed constructor, combinatorial inheritance, prototype inheritance parasitic inheritance and parasitic combined inheritance. In order to facilitate the understanding of memory, I daydream about a process, a simple description of the 6 model.

The specific problem shows: white screen, only the boundary (upper right corner) has a rectangular color block.This is actually a problem when the framework does not have the stencil buff enabled on the Android phone when the reference Oenngl is set .

Because it gives one the ability to share notes, sketch directly on the work, and collaborate through the use of video, Notism users is able to iterate designs faster.
