oscillate along the normal vector, which maps the VBO to the client and changes in each frame. You can compare it with traditional vertex arrays in a way that compares performance. It uses two vertex buffers: one for vertex coordinates and normal vectors, and the other for storing indexes.

Previously, CG was used. Now, glsl is used and learning is required again. However, many of the two languages are the same. The following example is a simple program for drawing a triangle. Some new OpenGL features such as VBO (veretx buffer object) and VAO (vertex array object) are used. More and more development in the future, the programmable pipeline will certainly be the trend of the times. The contents of some of the original fixed pipelines in

VBO is used to store vertex data, including vertex colors, coordinates, normals, and indices of vertices.Vao is used to store information about how the graphics processor will use the data inside the VBO, and what coordinates are in the vertex data, which are the colors, and which are the normals.I've never been too clear about these before, so I guess there's a part of me that I don't understand, so I'm go

The speed comparison between the VBO and displaylist discussed in the previous two times has not been added with cropping (view frustum culling), rendering in my terrainProgramAfter the cropping function is added, the test shows that:1. After cropping is added, the frame rate of using VBO is equivalent to that of using displaylist to draw frames.2. No view frustum culling is performed. The observed terrain

In my recently written terrain renderingProgramIt is found that using vertex buffer cannot increase the frame rate. Using VBO can indeed increase the frame rate by at least twice, but can display lists achieve the speed of VBO? My video card is NVIDIA geforce FX 5700le, and the video card driver 81. 98. However, we found that using displaylists can save half of the video memory compared with
