All 3D graphics rasterizer servers for Crystal Space should implement this interface, as well as the iGraphics2D interface. The standard implementation is csGraphics3DSoftware.
|
Close a volumetric fog object. After the volumetric object is closed it should be rendered on screen (whether you do it here or in DrawFogPolygon is not important). |
|
Add a front or back-facing fog polygon in the current fog object.
Note that it is guaranteed that all back-facing fog polygons will have been added before the first front-facing polygon. fogtype can be:
|
|
Draw a pixmap using a rectangle from given texture. The sx,sy(sw,sh) rectangle defines the screen rectangle within which the drawing is performed (clipping rectangle is also taken into account). The tx,ty(tw,th) rectangle defines a subrectangle from texture which should be painted. If the subrectangle exceeds the actual texture size, texture coordinates are wrapped around (e.g. the texture is tiled). The Alpha parameter defines the transparency of the drawing operation, 0 means opaque, 255 means fully transparent. WARNING: Tiling works only with textures that have power-of-two sizes! That is, both width and height should be a power-of-two, although not neccessarily equal. |
|
Draw the projected polygon with light and texture. Debugging version. This one does not actually draw anything but it just prints debug information about what it would have done. |
|
Draw a polygon with special effects. This is the most rich and slowest variant of DrawPolygonXxx. (If you use these features) Warning! Do not rely on this method to handle Color keying under all circumstances. Color Keying will only work reliable in Mixmodes FX_Copy, FX_Add and FX_Transparent. When using FX_Multiply and FX_Multiply2, it depends very much on the driver if it works or not. For example the RivaTNT Detonator 0.48 driver can display Multiply with color keying, while newer versions can't. They will then not display anything at all. It is always safer to use a texture where transparent sections are white or 50% gray if you want to achieve transparent sections in Multiply, Multiply2. There are also some drivers (which I would consider buggy...), that won't display FX_Alpha correctly with Color Keying. I can't provide a valid workaround for that except using FX_Multiplay and FX_Add, to manually create the image, but that would be very expensive. |
|
Get the current driver's capabilities. Each driver implements their own function. |
|
Get the vertex buffer manager. This will not increment the ref count of the vertex buffer manager! |
|
Initiate a volumetric fog object. This function will be called before front-facing and back-facing fog polygons are added to the object. The fog object will be convex but not necesarily closed. The given CS_ID can be used to identify multiple fog objects when multiple objects are started. |
|
Print the image in backbuffer. The area parameter is only a hint to the renderer. Changes outside the rectangle may or may not be printed as well. |
|
Remove some polygon from the cache. You have to call this function before deleting a polygon (csPolygon3D destructor will do that). |
|
Reset near clip plane (i.e. disable it). |
|
Set optional clipper to use. If clipper == null then there is no clipper. Currently only used by DrawTriangleMesh. |
|
Set near clip plane. Currently only used by DrawTriangleMesh. |
|
Set center of projection for perspective projection. Center is set in screen space coordinates. |
