1. Let, you can declare a variable by using allow instead of Var. Variables with let declarations have block-level scopes that take effect only in code blocks2. const, using const declaration constants, once declared, cannot be changed3. Pattern

Suppose you want to draw a 32*32 image at the point (x, y) and rotate it in the center of the image, use the following CodeThen you can rotate glfloat vertices [] = {-imagewidth/2,-imageheight/2, imagewidth/2,-imageheight/2,-imagewidth/2,

1. Rotate function: Glrotatef (float angle, float X, float Y, float Z) Where angle specifies the angle of the rotation of the object, x,y,z three parameters to determine the direction of the rotation axis. That is, the GLROTATEF function rotates

  The fog effect is actually very easy to implement. I will summarize it first: (1) first, we must set the background color to the fog color. (2) Enable the fog Effect (3) set the background color of fog (4) set the fog Equation The fog equation has

CodeNot very standard. Let's take a look. SDK version 15 can reduce the version compilation by itself. No new features are used. OpenGL currently has very few examples. If you are interested, you can download it and see it. It took me a day.All

If you reference an online record: For both, you pass OpenGL some buffers containing vertex data. GlDrawArrays is basically "draw this contiguous range of vertices, using the data I gave you earlier". Good: You don't need to build an index bufferBad:
