以下程序是一个 X 窗口系统 OpenGL 程序,其 OpenGL 代码与 AUXEDEMO 中使用的代码相同。Microsoft平台 SDK 提供的 C 示例程序。 将此程序与 移植到 Windows的程序中的 Windows OpenGL 程序进行比较。 C++ 复制 /* * Example of an X Window System OpenGL program. * OpenGL code is taken from auxdemo....
Texture warm-up is a technique that avoids draw-time frame rate stutters when glTexStorage and immutable format textures aren't available - for example, when targeting a device that only supports OpenGL ES 2.0. Because it is possible to modify the texture's properties for all mipmap levels,...

As you can see, GLSL looks similar to C. Each shader begins with a declaration of its version. Since OpenGL 3.3 and higher the version numbers of GLSL match the version of OpenGL (GLSL version 420 corresponds to OpenGL version 4.2 for example). We also explicitly mention we're using core...
AVertex ShaderinOpenGL is a pieceofClike code written to theGLSLspecification which influences the attributesofa vertex.Vertex shaders can be used to modify propertiesofthe vertex suchasposition,color,and texture coordinates.AFragment Shader is similar to a Vertex Shader,but is usedforcalculating in...

//OpenGL Code Example const GLchar *varyingOutCloudFeed[] = {"Varying.position", "Varying.cloudcount", "Varying.dimension"}; glTransformFeedbackVaryings(m_CloudFeedShader.GetProgramHandler(), 3, varyingOutCloudFeed, GL_SEPARATE_ATTRIBS); ...
Function pointers are generally declared in two parts;(函数指针通常被定义成两个部分) the first is the definition ofthe function pointer type, and the second is the function pointer variable itself.(第一个部分是函数的指针类型,第二个部分是函数指针本身) Consider this code as an example:(例如下面...
Glium provides easier ways to do common tasks. For example theVertexBufferstruct contains information about the vertex bindings, because you usually don't use several different bindings with the same vertex buffer. This reduces the overall complexity of OpenGL. ...
