Create a 3D texture using the GL_PROXY_TEXTURE_3D target.

This is used to download raw data from the texture into a pixel buffer.
The pixel buffer API can then be used to download the pixel buffer data to CPU arrays. The caller takes on the responsibility of deleting the returns vtkPixelBufferObject once it done with it.

Query and return maximum texture size (dimension) supported by the OpenGL driver for a particular context.
It should be noted that this size does not consider the internal format of the texture and therefore there is no guarantee that a texture of this size will be allocated by the driver. Also, the method does not make the context current so if the passed context is not valid or current, a value of -1 will be returned.

int | width, | ||
int | height | ||
) |
Copy a sub-part of a logical buffer of the framebuffer (color or depth) to the texture object.
src is the framebuffer, dst is the texture. (srcXmin,srcYmin) is the location of the lower left corner of the rectangle in the framebuffer. (dstXmin,dstYmin) is the location of the lower left corner of the rectangle in the texture. width and height specifies the size of the rectangle in pixels. If the logical buffer is a color buffer, it has to be selected first with glReadBuffer().
void vtkTextureObject::GetShiftAndScale | ( | float & | shift, |
float & | scale | ||
) |
Get the shift and scale required in the shader to return the texture values to their original range.
This is useful when for example you have unsigned char data and it is being accessed using the floating point texture calls. In that case OpenGL maps the uchar range to a different floating point range under the hood. Applying the shift and scale will return the data to its original values in the shader. The texture's internal format must be set before calling these routines. Creating the texture does set it.
