I am pretty new to OPENGL, and could any one help me ? thanks !!
I have a texture which contains number of tiles (each tile is part of this texture).
now I want to draw all the tiles in one draw call : glDrawElements(), (every tile's vertex coordination is different).
glVertexPointer(); //set the vertex array,
glTexCoordPointer(); //set the coordinations of the tile in texture.
do I have to call glTexCoordPointer() to set the coordinations for every tile ? that will be 3 times call of above code if I want to draw 3 tiles.
is there any efficient way to handle that ?
thank you very much !!
