Phase 1: buffers
engine:
provides the following hooks and methods
A) render target "color", and "matinfo". these correspond to texture[0] = "#color"; texture[2] = "#matinfo"; entries in scripts
B) utilizes the independentMrtBitDepth method added GarageGames#857 to set color to an 8RGBA if cards support it
C) adds an RenderPrePassMgr::_initShaders() method to support void RenderPrePassMgr::clearBuffers(). This operates as a pseudo-postfx by rendering a veiwspace plane which fills the screen, then calls a shader which fills both the introduced rendertarget buffers and the prepass buffer to relevant defaults (white with full alpha for prepass, black with full alpha for color and material respectively)
script:
\game\tools\worldEditor\main.cs adds additional hooks similar to GarageGames#863 for colorbuffer, specular map, and backbuffer display
\game\core\scripts\client\lighting\advanced\deferredShading.cs adds the clearbuffer shader, visualizers, and the ShaderData( AL_DeferredShader ) + PostEffect( AL_DeferredShading ) which combine the various buffers into the output which reaches the screen under normal conditions, as well as the extended debug visualizers.
again, note the lines
texture[0] = "#color";
texture[1] = "#lightinfo";
texture[2] = "#matinfo";
target = "$backBuffer";
in particular for the core tie-in.
shader:
\game\shaders\common\lighting\advanced\deferredColorShaderP.hlsl
\game\shaders\common\lighting\advanced\gl\deferredClearGBufferP.glsl
the previously mentioned shaders which clear the buffers to specified colors
\game\shaders\common\lighting\advanced\deferredShadingP.hlsl
\game\shaders\common\lighting\advanced\gl\deferredShadingP.glsl
the tie-in shaders
the rest are visualizers
purpose: to expose methodology that allows one to render color, lighting and material information such as specular and gloss which effect the result of both when combined
long term intent: the previous prepass lighting methodology while serviceable, unfortunately had the side effect of throwing out raw color information required by more modern pipelines and methodologies. This preserves that data while also allowing the manipulation to occur only on a screenspace (or reflected speudo-screenspace) basis.
pure script, there will be several of these using identical methodology for deferred. displays a given buffer via the
texture[0] = "#glowbuffer"; entry,
passed along to a given shader via the
samplerNames[0] = "glowBuffer";entry
which corresponds to an expected variable name and register.
as much documentation for later as tool
This commit adds a "Coverage" option to the procedural terrain
generator. Allows mixing of textures. See
http://www.garagegames.com/community/blogs/view/22371 for more info.
This version has many improvements - coverage is now entered as a
percentage, accepts decimals, and doesn't have any bugs as far as I
know.
This effectively duplicates (where necessary) and moves tools specific GuiProfiles out of the core and into the tools. This will allow future modifications to either the game guis or tools guis that use these profiles to not conflict with each other.
