renderPrePassMgr.cpp related:
A) shifting .addFeature( MFT_XYZ); calls from ProcessedShaderMaterial::_determineFeatures to ProcessedPrePassMaterial::_determineFeatures
B) mimicking the "// set the XXX if different" entries from RenderMeshMgr::render in RenderPrePassMgr::render
C) fleshing out ProcessedPrePassMaterial::getNumStages() so that it shares a 1:1 correlation with ProcessedShaderMaterial::getNumStages()
D) causing inline void Swizzle<T, mapLength>::ToBuffer( void *destination, const void *source, const dsize_t size ) to silently fail rather than fatally assert if a source or destination buffer is not yet ready to be filled. (support for #customTarget scripted render targets)
Reflections:
A) removing reflectRenderState.disableAdvancedLightingBins(true); entries. this would otherwise early out from prepass and provide no color data whatsoever.
B) removing the fd.features.addFeature( MFT_ForwardShading ); entry forcing all materials to be forward lit when reflected.
C) 2 things best described bluntly as working hacks:
C1) when reflected, a scattersky is rotated PI along it's z then x axis in order to draw properly.
C2) along similar lines, in terraincellmaterial, we shut off culling if it's a prepass material.
Skies: scattersky is given a pair of rotations for reflection purposes, all sky objects are given a z value for depth testing.
A lot of instances where some function args are not actually modified in any way, meaning that it is better for performance to convert them into const references. This prevents an additional copy, which can help performance.
- Updated to work with 0.5.x SDK
- Uses Oculus Rendering rather than PostFX
- Stereo rendering refactored so more rendering info is grabbed from the DisplayDevice
- Implements an Offscreen Canvas for in-game gui with oculus
- Message dialogs and metrics display can now go to the OffScreen Canvas (if oculus demo is setup correctly)
OpenGL and DirectX11 not support FFP, and GFDevice::disableShaders has not the necessary information to decide the shader to be used.
GFDevice::SetupGenericShaders is used instead of GFDevice::disableShaders.
GFDevice::disableShaders will be deprecated on T3D 4.0
During side-by-side rendering the refraction texture needs to be updated
for both the left and right fields. These changes add a new GFXDevice
event type to track when a field is about to be rendered. The
ReflectionManager listens to this new event and ensures that the
refraction texture will be updated if it is referenced by a material.
- Added an option for a postFX to get its viewport from a named texture
in slot 0, if there is one. This allows the postFX to operate when the
named input texture's viewport is different than the current viewport.
- Modified the SSAO postFX to use the new
PFXTargetViewport_NamedInTexture0 option to more closely link SSAO with
the prepass buffer.
- Modifed the GFX method setActiveRenderTarget() with a new parameter
that indicates if the current viewport should be modified with the new
rendering target. This defaults to true to maintain its previous
behaviour. The postFX rendering pipeline sets this to false as it now
handles its own viewport setup, and removes an unnecessary
GFX->setViewport() call.
- Side by side rendering implemented throughout the graphics pipeline.
- New GuiTSCtrl renderStyle property is set to "stereo side by side" to
activate.
- You set an IDisplayDevice on the GameConnection to define any vertical
FOV, projection offset, and stereo eye offset properties required for
the stereo rendering (no display device included with this commit).
- Full and Empty templates updated with correct scripts and shaders.
