WebI'm currently learning OpenGL and have been building a very basic engine that abstracts a lot of the common code away. Right now I have a VAO,VBO and a Shader class. From that I can draw the simple triangle into the window. Now I want to draw multiple shapes on the screen and I can do that if I have multiple VAO and VBO's but that seems Overkill.

A vertex buffer object (VBO) is an OpenGL feature that provides methods for uploading vertex data (position, normal vector, color, etc.) to the video device for non-immediate-mode rendering. VBOs offer substantial performance gains over immediate mode rendering primarily because the data reside in video device memory rather than system memory and so it can be rendered directly by the video device. These are equivalent to vertex buffers in Direct3D. Web2 de abr. de 2024 · The target parameter is just like the one for glBindBuffer; it says which bound buffer to modify. size represents how many bytes you want to allocate in this buffer object. data is a pointer to an array of bytes of size in length.
