OpenGL ES 1.0 was released publicly July 28, 2003. OpenGL ES 1.0 is based on the original OpenGL 1.3 API, with much functionality removed and a little bit added. ![]() One significant difference between OpenGL and OpenGL ES is that OpenGL ES removed the need to bracket OpenGL library calls with glBegin and glEnd. Other significant differences are that the calling semantics for primitive rendering functions were changed in favor of vertex arrays, and fixed-point data types were introduced for vertex coordinates. Many other functions and rendering primitives were removed in version 1.0 to produce a lightweight interface, including: Attributes were also added to better support the computational abilities of embedded processors, which often lack a floating point unit (FPU).polygon mode and antialiased polygon rendering are not supported, although rendering using multisample is still possible (rather than alpha border fragments).ARB_Image pixel class operation are not supported, nor are bitmaps or 3D textures.several of the more technical drawing modes are eliminated, including frontbuffer and accumulation buffer.Bitmap operations, specifically copying pixels (individually) is not allowed, nor are evaluators, nor (user) selection operations,. ![]()
