Alexander Szpakowski	3047321e71	Use initializer list copy constructor instead of per-element copying for shader source list in ShaderEffect constructor	2012-12-23 00:29:23 -04:00
Alexander Szpakowski	83204c5dc5	ShaderEffects now take a dynamically sized list of source codes instead of one vertex and one fragment shader string	2012-12-22 22:47:07 -04:00
Alexander Szpakowski	b55de47fb9	misc cleanup	2012-12-22 05:37:34 -04:00
Alexander Szpakowski	0c525ebb92	shaders now use a static vector of counters for each texture unit to help keep track of completely free texture units	2012-12-22 01:35:36 -04:00
Alexander Szpakowski	79fa42d207	made ShaderEffects individully handle texture units for sent images/canvases, added GL helper function for quickly binding a texture to a specific texture unit, hopefully made ShaderEffects load and unload volatile better	2012-12-22 00:29:11 -04:00
Alexander Szpakowski	16f925affa	improved GL texture binding api to take texture units into consideration	2012-12-21 20:35:32 -04:00
Alexander Szpakowski	5626b74b79	reduced unnecessary usage of glUseProgram, shadereffect is now properly detached in unloadVolatile and reattached if necessary in loadVolatile, made current and max texture units static to prevent different shaders from overwriting the value of different texture units	2012-12-21 17:43:47 -04:00
Alexander Szpakowski	5252ed28cd	changed shadereffect texture image unit counter and map to be non-static, get max texture units from max combined TIUs instead of max fragment shader TIUs, added the current MVP matrix as an argument to the vertex shader transform function, reduced code duplication in ShaderEffect::sendImage and sendCanvas	2012-12-21 05:03:50 -04:00
Alexander Szpakowski	0611234067	changed PixelEffect name to ShaderEffect, added lua-side support for vert/frag shader combinations with love.graphics.newShaderEffect, added tentative support for single-file vertex+fragment shaders	2012-12-20 21:51:31 -04:00
