Detailed Description
This is the standard 3D graphics interface.All 3D graphics rasterizer servers for Crystal Space should implement this interface, as well as the iGraphics2D interface. The standard implementation is csGraphics3DSoftware.
Main creators of instances implementing this interface:
- OpenGL Renderer plugin (crystalspace.graphics3d.opengl)
- Software Renderer plugin (crystalspace.graphics3d.software)
- Null 3D Renderer plugin (crystalspace.graphics3d.null)
Main ways to get pointers to this interface:

Member Function Documentation
|
Activate all given buffers.
|
|
Activate the buffers in the default buffer holder.
|
|
Start a new frame (see CSDRAW_XXX bit flags).
|
|
Close the 3D graphics display.
|
|
Close a portal previously opened with OpenPortal(). If 'zfill_portal' then the portal area will be zfilled. |
|
Create a halo of the specified color and return a handle.
|
|
Deactivate all given buffers. If attribs is 0, all buffers are deactivated; |
|
Disables offsetting of Z values.
|
|
Draw a line in camera space. Warning! This is a 2D operation and must be called while in BeginDraw(CSDRAW_2DGRAPHICS)! |
|
Drawroutine. Only way to draw stuff.
|
|
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 a csSimpleRenderMesh on the screen. Simple render meshes are intended for cases where setting up a render mesh and juggling with render buffers would be too much effort - e.g. when you want to draw a single polygon on the screen. DrawSimpleMesh () hides the complexity of csRenderMesh, it cares about setting up render buffers, activating the texture etc. Note that you can still provide shaders and shader variables, but those are optional.
|
|
Enables offsetting of Z values.
|
|
End the frame and do a page swap.
|
|
Get the current driver's capabilities. Each driver implements their own function. |
|
Get clipper that was used.
|
|
Return type of clipper.
|
|
Retrieve the associated canvas.
|
|
Get drawing buffer height.
|
|
Get near clip plane.
|
|
Get aspect ratio.
|
|
Get perspective center.
|
|
Get a renderstate value.
|
|
Get the current render target (0 for screen).
|
|
Retrieve the texture manager.
|
|
Get drawing buffer width.
|
|
Get the masking of color and/or alpha values to framebuffer.
|
|
Get Z-buffer value at given X,Y position.
|
|
Get the z buffer write/test mode.
|
|
Return true if we have a near plane.
|
|
Open the 3D graphics display.
|
|
Enter a new portal. If 'flags' contains CS_PORTAL_FLOAT then this routine will restrict all further drawing to the given 2D area and it will also respect the current contents of the Z-buffer so that geometry will only render where the Z-buffer allows it (even if zfill or znone is used). Remember to close a portal later using ClosePortal(). Basically this represents a stacked layer of portals. Each subsequent portal must be fully contained in the previous ones. |
|
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. |
|
Change the dimensions of the display.
|
|
Set near clip plane.
|
|
Set a renderer specific option. Returns false if renderer doesn't support that option. |
|
Set aspect ratio for perspective projection.
|
|
Set center of projection for perspective projection.
|
|
Set a renderstate value.
|
|
Set the target of rendering. If this is 0 then the target will be the main screen. Otherwise it is a texture. After calling g3d->FinishDraw() the target will automatically be reset to 0 (main screen). Note that on some implementions rendering on a texture will overwrite the screen. So you should only do this BEFORE you start rendering your frame. If 'persistent' is true then the current contents of the texture will be copied on screen before drawing occurs (in the first call to BeginDraw). Otherwise it is assumed that you fully render the texture. |
|
Controls shadow drawing.
|
|
Activate or deactivate all given textures depending on the value of 'textures' for that unit (i.e. deactivate if 0). |
|
Set the world to camera transform. This affects rendering in DrawMesh and DrawSimpleMesh.
|
|
Set the masking of color and/or alpha values to framebuffer.
|
|
Set the z buffer write/test mode.
