Cylinder VBO OpenGL: What am I doing wrong?
Cylinder VBO OpenGL: What am I doing wrong?
this one helps. The problem is the size you are passing to glBufferData: sizeof(bufferData) is the same as std::vector and has nothing to do with the size of the vectors data.What you have to do is to pass the actual size of the data stored in the ve

OpenGL - Why are my Z coords 2x scale?
OpenGL - Why are my Z coords 2x scale?
I hope this helps . Transformation matrices are only half of the truth. In modern GL, the vertex shader (or more precisely: all programmable stages before the rasterizer) are responsible for the transformation of object space coordinates into clip sp

GLGenVertexArrays giving me an invalid memory address
this will help All functions and extensions of OpenGL > 1.1 have to be loaded in order to be used. This can be done, for example, by using glew which has to be initialized as follows:

help you fix your problem When changing the orientation of the y-axis, also the winding order of the primitives changes. So if backface culling is enabled, one has to adjust the winding order by setting it with

Fragment Shader IN variable causes nothing to appear
Fragment Shader IN variable causes nothing to appear
I hope this helps you . int variables cannot be interpolated by the GL. You must declare both the output and the corresponding input with the flat qualifier`.From the behavior you described, it seems like you are not properly checking the compile and

I think the issue was by ths following , I think CCSprite/CCLayerColor/CCLayerGradient with CCClippingNode can simulate the "smart brush", and tintTo/tintBy action of CCSprite/CCLayerColor can change color without destroying the object

Weird result with MSAA
Weird result with MSAA
seems to work fine MSAA only helps to smooth polygon edges and intersections. It does nothing to smoothen sharp transitions created by your shader code.The main idea behind MSAA is that the fragment shader is still executed only once per fragment. Ea

Why is scissor test behind fragment operation?
Why is scissor test behind fragment operation?
I wish did fix the issue. The scissor test will in almost any real-world scenario affect the rasterization itself. The GPU's rasterizer units will not produce fragments outside of the scissor rect. When the OpenGL pipeline was first created, the frag
