opengl can now compile with ubo buffer objects similar to cbuffers on dx side.
cleaned double up of data from both sides, gfxhandles only need to use the desc info instead of holding onto its own.
Workaround: MacOS does not have access to glClipControl.
Because the lower range of the 32F buffer is not available using this workaround, the improvements to depth behavior from depth reversal will be limited on MacOS. Behavior is equivalent to reversed depth on a 24UINT buffer; Better than stock, but not dramatically.
-Adds reversed depth projection model, dramatically increasing depth buffer effective resolution.
-Adds 32F depth 8U stencil format GFXFormatD32FS8X24 (following DX naming conventions). Note this is a 64-bit format, and likely not suitable for mobile platforms. Revert to GFXFormatD24S8 in renderManager.tscript for mobile & "ancient" platforms.
-Corrects alignment of texture type details array.
Swapped the water's disableTrueReflections variable to be enableTrueReflections for simplicity and consistency(also fixed a persistent typo)
Swapped disableVerticalSync to be enableVerticalSync for simplicity and consistency
Swapped disableParallaxMapping to be enableParallaxMapping for simplicity and consistency
Fix click detection on slider mode entries for guiGameSettingsCtrl so the click position correctly matches the percentage
Fixed problem where postFX initialization would always exec default.postfxpreset.tscript, even if a level's got it's own preset, which can cause problems
Fixed range field type behavior so that editing the values applies in real time, and also consistently applies between slider and text field
GL layer was missing _captureBackBuffer() implementation which caused screenShot() function to fail. Also caused ScreenShot::capture() to be called every frame afterward which caused significant performance issues.
largely cleanups, though does include glCopyImageSubData for gl revs that support it
TODOS:
1) non glCopyImageSubData for `void GFXGLCubemapArray::copyTo(GFXCubemapArray *pDstCubemap)`
2) while we don't get corruption showing in >0 mips for irradiance maps using the newer code, it nevertheless renders wrong.
not 100% sure if renderdoc is showing blank mips because it expects it due to size, or if we are in fact generating em even though we don't use em in the end for irradiance references.
This makes some tweaks to the engine to support this, specifically, it tweaks the hardcoded shaderpaths to defer to a pref variable, so none of the shader paths are hardcoded.
Also tweaks how post effects read in texture files, removing a bizzare filepath interpretation choice, where if the file path didn't start with "/" it forcefully appended the script's file path. This made it impossible to have images not in the same dir as the script file defining the post effect.
This was changed and the existing template's post effects tweaked for now to just add "./" to those few paths impacted, as well as the perf vars to support the non-hardcoded shader paths in the engine.
while not a major issue per-se, the sheer number of times the engine has to jump back in memory and backfill data in a given class can add up. First run of... many.,
- Supports GL, D3D9 & D3D11
- Extends vertex formats & shadergen to support blend indices and weights
- Adds basic support for using 4x3 matrices for shader constants
- Supports software fallback
