OpenGL ES 1.x


This extension extends the standard functionality of OpenGL points to allow more flexible rendering than otherwise provided. For a core point object, OpenGL ES specifies that texture coordinates are identical across the entire body of the point, and it is then anti-aliased to fade out. To work around this, developers often use a quad with an alpha blended/tested texture to allow the full range of a texture to be expressed. When in use, this extension disables the anti-aliasing on the point, and instead interpolates the texture coordinates provided over the entire body of the point, allowing a point to be effectively textured to represent a sprite.


This functionality is core to OpenGL ES 2.0 and 3.0.

Registry Link


// Enable point sprite drawing 
// Set the texture environment to use point sprite coordinate replace to true, so that texture 
// coordinates are interpolated automatically across the rendered point, rather than using a 
// single coordinate. 
// Draw some point sprites at the locations specified in  
glDraw(GL_POINTS, ...);
