Interface to driver which is able to perform 2d and 3d graphics functions.
This interface is one of the most important interfaces of the Jimcpp Engine: All rendering and texture manipulation is done with this interface. You are able to use the Jimcpp Engine by only invoking methods of this interface if you like to, although the jpp::scene::ISceneManager interface provides a lot of powerful classes and methods to make the programmer's life easier.
adds a dynamic light, returning an index to the light
| light | the light data to use to create the light |
|
pure virtual |
Adds an external image loader to the engine.
This is useful if the Jimcpp Engine should be able to load textures of currently unsupported file formats (e.g. gif). The IImageLoader only needs to be implemented for loading this file format. A pointer to the implementation can be passed to the engine using this method.
| loader | Pointer to the external loader created. |
|
pure virtual |
Adds an external image writer to the engine.
This is useful if the Jimcpp Engine should be able to write textures of currently unsupported file formats (e.g .gif). The IImageWriter only needs to be implemented for writing this file format. A pointer to the implementation can be passed to the engine using this method.
| writer | Pointer to the external writer created. |
|
pure virtual |
Adds a new material renderer to the video device.
Use this method to extend the VideoDriver with new material types. To extend the engine using this method do the following: Derive a class from IMaterialRenderer and override the methods you need. For setting the right renderstates, you can try to get a pointer to the real rendering device using IVideoDriver::getExposedVideoData(). Add your class with IVideoDriver::addMaterialRenderer(). To use an object being displayed with your new material, set the MaterialType member of the SMaterial class to the value returned by this method. If you simply want to create a new material using vertex and/or pixel shaders it would be easier to use the video::IGPUProgrammingServices interface which you can get using the getGPUProgrammingServices() method.
| renderer | A pointer to the new renderer. |
| name | Optional name for the material renderer entry. |

Clears the ZBuffer.
Note that you usually need not to call this method, as it is automatically done in IVideoDriver::beginScene() or IVideoDriver::setRenderTarget() if you enable zBuffer. But if you have to render some special things, you can clear the zbuffer during the rendering process with this method any time.

The 2d override material allows to alter certain render states of the 2d methods. Not all members of SMaterial are honored, especially not MaterialType and Textures. Moreover, the zbuffer is always ignored, and lighting is always off. All other flags can be changed, though some might have to effect in most cases. Please note that you have to enable/disable this effect with enableMaterial2D(). This effect is costly, as it increases the number of state changes considerably. Always reset the values when done.

Set or unset a clipping plane.
There are at least 6 clipping planes available for the user to set at will.
| index | The plane index. Must be between 0 and MaxUserClipPlanes. |
| plane | The plane itself. |
| enable | If true, enable the clipping plane else disable it. |

Sets the fog mode.
These are global values attached to each 3d object rendered, which has the fog flag enabled in its material.
| color | Color of the fog |
| fogType | Type of fog used |
| start | Only used in linear fog mode (linearFog=true). Specifies where fog starts. |
| end | Only used in linear fog mode (linearFog=true). Specifies where fog ends. |
| density | Only used in exponential fog mode (linearFog=false). Must be a value between 0 and 1. |
| pixelFog | Set this to false for vertex fog, and true if you want per-pixel fog. |
| rangeFog | Set this to true to enable range-based vertex fog. The distance from the viewer is used to compute the fog, not the z-coordinate. This is better, but slower. This might not be available with all drivers and fog settings. |
|

Sets a material.
All 3d drawing functions will draw geometry using this material thereafter.
| material | Material to be used from now on. |
|
pure virtual |
Sets the name of a material renderer.
Will have no effect on built-in material renderers.
| idx | Id of the material renderer. Can be a value of the E_MATERIAL_TYPE enum or a value which was returned by addMaterialRenderer(). |
| name | New name of the material renderer. |
|
pure virtual |
Set the minimum number of vertices for which a hw buffer will be created.
| count | Number of vertices to set as minimum. |

Sets a new render target. Prefer to use the setRenderTarget function taking flags as parameter as this one can't clear the stencil buffer. It's still offered for backward compatibility.

Sets a new render target.
This will only work if the driver supports the EVDF_RENDER_TO_TARGET feature, which can be queried with queryFeature(). Usually, rendering to textures is done in this way:
Please note that you cannot render 3D or 2D geometry with a render target as texture on it when you are rendering the scene into this render target at the same time. It is usually only possible to render into a texture between the IVideoDriver::beginScene() and endScene() method calls.
| texture | New render target. Must be a texture created with IVideoDriver::addRenderTargetTexture(). If set to 0, it sets the previous render target which was set before the last setRenderTarget() call. |
| clearFlag | A combination of the E_CLEAR_BUFFER_FLAG bit-flags. |
| clearColor | The clear color for the color buffer. |
| clearDepth | The clear value for the depth buffer. |
| clearStencil | The clear value for the stencil buffer. |

Enables or disables a texture creation flag.
These flags define how textures should be created. By changing this value, you can influence for example the speed of rendering a lot. But please note that the video drivers take this value only as recommendation. It could happen that you enable the ETCF_ALWAYS_16_BIT mode, but the driver still creates 32 bit textures.
| flag | Texture creation flag. |
| enabled | Specifies if the given flag should be enabled or disabled. |

Sets transformation matrices.
| state | Transformation type to be set, e.g. view, world, or projection. |
| mat | Matrix describing the transformation. |
|
pure virtual |
Sets a new viewport.
Every rendering operation is done into this new area.
| area | Rectangle defining the new area of rendering operations. |
|
pure virtual |
Swap the material renderers used for certain id's.
Swap the IMaterialRenderers responsible for rendering specific material-id's. This means every SMaterial using a MaterialType with one of the indices involved here will now render differently.
| idx1 | First material index to swap. It must already exist or nothing happens. |
| idx2 | Second material index to swap. It must already exist or nothing happens. |
| swapNames | When true the renderer names also swap When false the names will stay at the original index |

Turns a dynamic light on or off
| lightIndex | the index returned by addDynamicLight |
| turnOn | true to turn the light on, false to turn it off |

Update all occlusion queries. Retrieves results from GPU.
If the query shall not block, set the flag to false. Update might not occur in this case, though

Writes the provided image to a file.
Requires that there is a suitable image writer registered for writing the image.
