The Geometries of Balder provides many existing models, such as cubes and columns. However, when developing games, we usually use 3D design tools to create custom 3D models, this article describes how to import and display a custom 3D model. First, let's look at the built-in Geometries model. You can view it in the object browser or Geometries. The Heightmap in it will be introduced later. This time we will mainly introduce Mesh (Mesh object) and use it to import custom models. Then, prepare a

cylinder in the z direction; slices indicates the number of segments along the central axis, and stacks indicates the number of "heaps" along the main axis. (Note: similar to the number of blocks in the horizontal and vertical directions divided by longitude and weft.) mesh = mesh. polygon (device, 2.0f, 8); Length indicates the length of each side of the polygon, and sides indicates the number of edges mesh = mesh. sphere (device, 2.0f, 36, 36); radius indicates the sphere radius.

The styling comes from a simple teapot that is common in life. It is made into a mathematical model with solid, cylindrical and partial surfaces.The

This tutorial introducesToon shader)Method,Cartoon rendering is a non-photorealistic rendering or a type. Cartoon rendering an object looks like a cartoon painting. Here is a simple method for rendering cartoon effects. Unlike general light rendering, the color transition between the pixels of objects rendered by cartoon effects is a step function, the color transition of objects rendered by light is a smooth continuous function. Figure 1 compares the cartoon rendering with the pixel-based rende

of imagining a matrix in 2D is to imagine the "L" shape composed of row vectors. In this example, we can clearly see that,MIt indicates that the part is rotated 26 degrees counter-clockwise. Of course, all vectors are affected by linear transformation, not just base vectors. The most intuitive impression of transformation can be obtained from the "L" shape, the Complete 2D parallelogram composed of the base vector helps to further see the impact of the transformation on other vectors, as shown

Gouraud ). Each pixel calculates light separately. 2nd sheets: The colors are flat, Gouraud, and Phong respectively. Compared to the 1st images, the mirror light is added (note that the white spot appears in many places of the teapot ). 3rd sheets: Texture is introduced on the basis of the previous one. Pay attention to the spot on the nozzle. The depth buffer is not enabled for this group of images, so the display is incorrect. 4th sheets: High

Forget when in where to see a rotating effect, the brain is hot, just I just learned a little 3DMAX, I imitated such a super simple super naïve effect. I hope we can borrow methods do not borrow effect, or I have become a sinner, fraught may not be good, good, I immediately introduce the general practice: First of all you want to 3DMAX, not too strong, I am also rookie level, but w

the blog that tells reflected Light. Instance parsing Well, the theory is over. Below, we use the spotlight to make a simple demo. Similarly, we use a teapot prototype to do it. We draw a teapot on the x-z plane so that when the spotlight gathers in a certain part, it can be seen clearly. Here is the code that draws a teapot: void Cubedemo::d raw () {//set the

It is inevitable that the tea set will be stained with dust and dirt. You must wash the tea with clear water carefully. Before brewing and pouring tea, it is best to boil the teapot and cup with boiling water. In this way, it is both hygienic and polite. It is impolite to pour tea to the guests regardless of whether
