const [virtual] |
Number of mip levels. Used to compensate for varied image source depths.
Implements IClipMapImageSource.
| virtual void AtlasClipMapImageSource::setInterestCenter |
( |
const Point2I & |
origin, |
|
|
const U32 |
radius | |
|
) |
| | [virtual] |
Set a new interest center for this image source.
This gives the source important cues for paging of content.
Implements IClipMapImageSource.

( |
const U32 |
mipLevel, |

| | const [virtual] |
True if the data for the specified mip level and region is available.
Implements IClipMapImageSource.
Copy bits from source into a locked texture buffer.
- Parameters:
-
| mipLevel | What mip level of the texture? |
| cse | Information about the clip stack layer we're uploading to. Can be NULL. |
| srcRegion | Region in pixels on this mip level to copy from. |
| bits | Pointer to beginning of locked buffer. |
| pitch | Stride in bytes from start of one row to start of next. |
Implements IClipMapImageSource.
| virtual bool AtlasClipMapImageSource::isTiling |
( |
|
) |
const [virtual] |
If true, this image source tiles itself infinitely; if the image source is tiling then the clipmap can also be tiling.
Specifically this means that the source can update a rectangle from any location in image-space as long as its extents are no bigger than the reported size of the image source.
Implements IClipMapImageSource.

| virtual F32 AtlasClipMapImageSource::texelOffset |
( |
|
) |
const [virtual] |
This is used to deal with geometry that wants texels to be at vertices vs.
geometry that wants texels to be in the center of the quad/triangle. Return 0 for centering, and 0.5 for vertex based.
Implements IClipMapImageSource.
