Transform from position to position, or scaling object's size is easy, but when it comes to rotation, I'm not quite able to handle it, any tutorials about this?

@DMGregory, I pasted my structure, according to you comment, my structure seems wrong. Can you show me some example of data structures on representing a "transform"?

@TomTsagk, I add some explaination. Since I'm new to graphics, if you don't understand, can you just illustrate what data structure to use to represent a "transform"?

That's very nice. I'm good at writing compilers, currently my plan is to write a parser to change a graph/custom code to the actual GLSL code. I'll come back if I get troubles. Thanks again for your help.

Thanks so much, I seem to understand a bit.

Hi, correct if I'm wrong: though a programmer(code) or a designer(graph tools) create shaders, but the final shader is still manipulated by the editor to make sure all is well, right? That's why even though I didn't do the coordinate transformation in the shader, the coordinate system still works fine?
