difference between opengl es 2.0 and 3.0

New functionality in the OpenGL ES 3.0 specification includes: OpenGL ES 3.0 is backwards compatible with OpenGL ES 2.0, enabling applications to incrementally add new visual features to applications. The OpenGL ES 3.0 specification was publicly released in August 2012. non-square and transposable uniform matrices.program binaries, including querying binaries from linked GLSL programs.ability to attach any mipmap level to a framebuffer object.draw command allowing specification of range of accessed elements.unsigned integer element indices with at least 24 usable bits.32-bit depth and 32F/8 depth/stencil renderbuffers and textures.24/8 depth/stencil renderbuffers and textures.24-bit depth renderbuffers and textures.8-bit unsigned normalized renderbuffers.sized internal texture formats with minimum precision guarantees.8-bit-per-component signed normalized textures.16-bit floating-point vertex attributes.10/10/10/2 signed and unsigned normalized vertex attributes.10/10/10/2 unsigned normalized and unnormalized integer textures.8-bit sRGB textures and framebuffers (without mixed RGB/sRGB rendering).32-bit, 16-bit, and 8-bit signed and unsigned integer renderbuffers, textures, and vertex attributes.16-bit (with filtering) and 32-bit (without filtering) floating-point textures.at least 32 textures, at least 16 each for fragment and vertex shaders.

texture LOD clamps and mipmap level base offset and max clamp.non-power-of-two textures with full wrap mode support and mipmapping.

simplified texture storage specification.

instanced rendering, via shader variable and/or vertex attribute divisor.boolean occlusion queries, including conservative mode.buffer object to buffer object copies 314.uniform buffer objects including block arrays.transform feedback 1 and 2 (with restrictions).Here is a listing of changes described in the spec linked to by Alexey: ETC2/EAC texture compression formats (Previously on Android each card manufacturer only supported their own texture formats).Depending on your platform it could be revolutionary, however many of the key features were already extensions on platforms such as iOS.įor my work personally, the most significant changes are: Additional features such as instanced rendering, pixel buffer objects, and occlusion queries, provide opportunities for optimization. Overall the changes increase flexibility with bigger buffers, more formats, more uniforms, etc. I think it would be best to read section 'Version 3.0 and Before -> New Features' on the official specsĪnd it is backward compatible with ES 2.0.
