It seems mine is turned around and is beginning from right to left. Do you know what causes it? As others have noted, you are pushing the nodes-to-visit-next on the stack in order from left to right. That means they get popped off right-to-left, since a stack reverses the order. Stacks are last-in-first-out. You can … Read more
From this I conclude that when rendering geometry which is all seams or mostly seams, when using GL_TRIANGLE_STRIP or _FAN, then I should never use indexed arrays, and should instead always use gl[Multi]DrawArrays. No, and the reason is quite simple. Your conclusion is based on the fact you have analysed a single quad composed by … Read more
There are no differences between the words Node and Vertex. Even in some books that explain graph theory and graph algorithms they name it as: Vertex denoted by v, and sometimes it’s called nodes also There are no major nor minor differences between them. This is mentioned in the book: Data structure and Algorithms with … Read more
The call to glBindBuffer tells OpenGL to use vertexBufferObject whenever it needs the GL_ARRAY_BUFFER. glEnableVertexAttribArray means that you want OpenGL to use vertex attribute arrays; without this call the data you supplied will be ignored. glVertexAttribPointer, as you said, tells OpenGL what to do with the supplied array data, since OpenGL doesn’t inherently know what … Read more
