Reading and displaying 3DS files in OpenGL After learning blender, I really want to load the model I designed into my own program. Therefore, I considered the common 3DS file format. This time I tried to load the 3DS file into my own OpenGL program and display it. Demo program: here Source code: here First, I found a lot of examples of loading the 3DS format ou

: Behavior that begins with # comment line USEMTL and mtllib represent the texture-related data, parsing texture data is a little cumbersome, this section we just to illustrate the principle of loading the model, not to discuss. o introduction of a new object V indicates vertex position VT represents vertex texture coordinates VN denotes vertex normal vector F represents a polygon, the polygon uses the format of 1/2/8, which represents the index of the vertex pos

The OpenGL Basic Library provides a large number of methods for drawing various types of elements, and the auxiliary Library also provides many functions to describe complex 3D images. This chapter mainly introduces basic elements, such as points, lines, and polygon. With these elements, you can create a complex model. 7.1. description elements OpenGL is a function library for 3D graphics. Its elements su

1. Necessary work before drawing 1.1 set the view area of the form (view port) Glviewport (X: glint; Y: glint; width: glsizei; Height: glsizei ); The parameters X and Y specify the position in the window in the lower-left corner of the visible area. Generally, they are (0, 0), and width and height specify the width and height of the visible area. Note that the window coordinates used by OpenGL are different from those used by windowsgdi.

See http://www.khw.s.org/on the official website,OpenGL ES 1.x For fixed function hardware: OpenGL ES 1.1 is defined relative to the OpenGL 1.5 specification and emphasizes hardware acceleration of the API, but is fully backwards compatible with 1.0. it provides enhanced functionality, improved image quality and Optimizations to increase performance while loading

ObjectiveIn the first 2 articles, we all talked about shaders, and in the second it was formally said that this shader can only be used in programmable pipelines such as OpenGL es2.x, but not in OpenGL es1.x. But we haven't been saying why, what's the difference between the two. Well, let's get this one together. Learn the rendering pipeline in OpenGL ES.BodyPipe

2.1 basic understanding of OpenGL OpenGL is a software interface with a hardware Graphics Generator. It includes more than 100 graphic operation functions. developers can use these functions to construct scene models and develop 3D graphics interaction software. As described in the previous chapter, OpenGL is a high-performance graphics development software packa
