Difference between opengl es 2.0 and 3.01/23/2024 This collection of documents describes the platform-specific APIs for OpenGL ES on iOS devices, also known as EAGL. The OpenGL ES framework ( amework) in iOS provides implementations of versions 1.1, 2.0, and 3.0 of the OpenGL ES specification. Render with painter's algorithm, where "render" means pushing the geometry into a vertex buffer, and draw it at the end. OpenGL ES provides a C-based interface for hardware-accelerated 2D and 3D graphics rendering. You want to avoid doing a draw call per sprite, as that is incredibly inefficient, and rather you want to batch together a lot of sprites and draw them all at once. In terms of 2D in OpenGL in general, just make sure you have a texture atlas (sprite sheet) so you very rarely need to change texture states. One significant difference between OpenGL and OpenGL ES is that OpenGL ES removed the need to. What are the differences between OpenGL ES 2.0 and OpenGL ES 3.0. However, in most cases for simple 2D, all you're going to be doing is filling up a streaming vertex buffer every frame and making a single draw call, so there's really very little extra you're going to be doing. Hi I am porting an OpenGL app to OpenGL ES 3.0 and I wonder if exists any equivalent function to glVertexAttribI2i void glVertexAttribI2i(GLuint index, GLint v0, GLint v1 ) The. If you're specifically asking about what features in OpenGL 3.0 are worth using, some of the best ones are geometry shaders and instancing, both of which are useful even for 2D graphics in certain circumstances. Most OpenGL implementations have most of the features of OpenGL 3.0+ even when using a legacy context, due to the way OpenGL extensions work. In terms of the contexts specifically, there's little difference.
