WebThe Textures example demonstrates the use of Qt's image classes as textures in applications that use both OpenGL and Qt to display graphics. WebDescription. glDrawElements specifies multiple geometric primitives with very few subroutine calls. Instead of calling a GL function to pass each individual vertex, normal, texture coordinate, edge flag, or color, you can prespecify separate arrays of vertices, normals, and so on, and use them to construct a sequence of primitives with a single ...

For example, with GLSL, you use the gl_Position variable to specify vertex position and the gl_FragColor variable to specify fragment color. In HLSL, you pass Direct3D state explicitly from the app code to the shader.
