* Use vec4 for varTexCoord in interlaced shader (#11004)Muhammad Rifqi Priyo Susanto2021-03-01
| | | Somewhen in the past, inTexCoord0 was a vec2. Now, it is a vec4.
* Shaders for Android (GLES 2) (#10506)Vitaliy2020-10-25
| | | | | Shader support for OpenGL ES 2 devices (Android) Co-authored-by: sfan5 <sfan5@live.de>
* Rewrite rendering engine (#6253)Vitaliy2017-10-31
* Clean draw_*() arguments * Split rendering core * Add anaglyph 3D * Interlaced 3D * Drop obsolete methods
