◆ addDecal() [1/2]

Shadow * W3DProjectedShadowManager::addDecal	(	RenderObjClass *	robj,
		Shadow::ShadowTypeInfo *	shadowInfo )

virtual

add a non-shadow decal

Generic function which can be used to create arbitrary decals that follow the renderObject but don't have to be used for shadows. Some examples: Scorch marks, blood, stains, selection/status indicators, etc.

type of projection

wrap shadow around world geometry - else align perpendicular to local z-axis.

Todo: : Fix projected shadows to allow multiple lights

empty queue by rendering all decals with given texture

◆ init()

Bool W3DProjectedShadowManager::init ( void )

allocate one-time shadow assets for length of entire game.

Definition at line 252 of file W3DProjectedShadow.cpp.

◆ invalidateCachedLightPositions()

void W3DProjectedShadowManager::invalidateCachedLightPositions ( void )

forces shadows to update regardless of last lightposition

Definition at line 326 of file W3DProjectedShadow.cpp.

◆ queueDecal()

void W3DProjectedShadowManager::queueDecal ( W3DProjectedShadow * shadow )

add shadow decal to render list - decal conforms to terrain.

Decals have a low poly count so its better to render large numbers at once. This system will queue them up until the buffers fill up. It will then flush the buffer (draw decals) and be ready for new decals. This is an optimized system that only uses the render objects bounding box to determine shadow visibility.

Todo: : Optimize this bounding box calculation to use transformed extents

Todo: : fix the winding order in heightmap to be in strip order like above!

Definition at line 811 of file W3DProjectedShadow.cpp.

◆ queueSimpleDecal()

void W3DProjectedShadowManager::queueSimpleDecal ( W3DProjectedShadow * shadow )

add shadow decal to render list - decal floats on terrain.

Simpler/faster decal system that always uses 2 triangles that are roughly oriented to terrain. Since they are not projected onto terrain, there may be clipping artifacts in certain situations. TODO: Too much clipping. Need to check terrain heights at all 4 corners and adjust tilt to match

Todo: : We should have a pre-made static filled index buffer since we always send down 2 triangles.

Definition at line 1154 of file W3DProjectedShadow.cpp.

◆ ReAcquireResources()

Bool W3DProjectedShadowManager::ReAcquireResources ( void )

allocate device dependent D3D resources.

Todo: : We should allocate our render target pool here.

Definition at line 263 of file W3DProjectedShadow.cpp.

◆ ReleaseResources()

void W3DProjectedShadowManager::ReleaseResources ( void )

release device dependent D3D resources.

Definition at line 314 of file W3DProjectedShadow.cpp.

◆ removeAllShadows()

void W3DProjectedShadowManager::removeAllShadows ( void )

Remove all shadows.

Definition at line 2084 of file W3DProjectedShadow.cpp.

◆ removeShadow()

void W3DProjectedShadowManager::removeShadow ( W3DProjectedShadow * shadow )

Definition at line 2028 of file W3DProjectedShadow.cpp.

◆ renderShadows()

Int W3DProjectedShadowManager::renderShadows ( RenderInfoClass & rinfo )

iterate over each object and render its shadow onto affected objects.

Todo: : implement this method.

Todo: : may need to fix this if shadows are large enough to be seen while object is not visible

Todo: : don't apply shadows to translcuent objects unless they are MOBILE - hack to get tanks to work.

◆ reset()

void W3DProjectedShadowManager::reset ( void )

free all existing shadows - ready for next map.

Definition at line 242 of file W3DProjectedShadow.cpp.

◆ shutdown()

void W3DProjectedShadowManager::shutdown ( void )

free all assets prior to shutdown of entire game.

◆ updateRenderTargetTextures()

void W3DProjectedShadowManager::updateRenderTargetTextures ( void )

render into any textures that need updating.

Todo: : Don't update texture for shadows that can't be seen!!
