/* The pixel format for the pbuffer is controlled by the mode string passed
|
||||
* into the PBuffer constructor. This string can have the following attributes:
|
||||
*
|
||||
* To specify the pixel format, use the following syntax.
|
||||
* <channels>=<bits>
|
||||
* <channels> must match one of the following.
|
||||
*
|
||||
* r - r pixel format (for float buffer).
|
||||
* rg - rg pixel format (for float buffer).
|
||||
* rgb - rgb pixel format. 8 bit or 16/32 bit in float buffer mode
|
||||
* rgba - same as "rgb alpha" string
|
||||
*
|
||||
* <bits> can either be a scalar--meaning the same bit depth for each
|
||||
* channel-- or a 2-, 3-, 4-component vector matching the specified number of
|
||||
* channels. Vector components should be comma separated. An optional 'f'
|
||||
* suffix on the bit depth specifies float components. In this case <bits>
|
||||
* must be either "32f" or "16f". If <bits> is empty, the default 8 bits per
|
||||
* channel will be used.
|
||||
* r=32f
|
||||
* rg=16f
|
||||
* rgb=8
|
||||
* rgb=5,6,5
|
||||
*
|
||||
* The following other attributes are supported.
|
||||
*
|
||||
* depth=n - must have n-bit depth buffer, omit n for default (24 bits)
|
||||
* stencil=n - must have n-bit stencil buffer, omit n for default (8 bits)
|
||||
* samples=n - must support n-sample antialiasing (n can be 2 or 4)
|
||||
* aux=n - must have n AUX buffers
|
||||
* doublebuffer - must support double buffered rendering
|
||||
*
|
||||
* tex2D
|
||||
* texRECT
|
||||
* texCUBE - must support binding pbuffer as texture to specified target
|
||||
* - binding the depth buffer is also supported by specifying
|
||||
* depthTex2D
|
||||
* depthTexRECT
|
||||
* depthTexCUBE
|
||||
* - Both depth and color texture binding, may be specified, but
|
||||
* the targets must match!
|
||||
* For example: "tex2D depthTex2D" or "texRECT depthTexRECT"
|
||||
*
|
||||
* rtt
|
||||
* ctt - These mutually exclusive options specify the update method used
|
||||
* for render textures that support texture binding. "rtt"
|
||||
* indicates that render to texture will be used to update the
|
||||
* texture. "ctt" indicates that copy to texture will be used
|
||||
* (i.e. glCopyTexSubImage2D()). "rtt" is the default if neither is
|
||||
* specified, and one of the "tex*" options above is.
|
||||
*
|
||||
*
|
||||
*---------------------------------------------------------------------------
|
||||
*
|
||||
* USAGE NOTES:
|
||||
*
|
||||
* * Texture Parameters:
|
||||
* The default texture wrap mode is GL_CLAMP_TO_EDGE for all textures, and
|
||||
* the default texture filtering modes (min and mag) are GL_NEAREST.
|
||||
* To change these parameters, simply bind the RenderTexture (using the
|
||||
* Bind() method), and set them the way you would for any GL texture object.
|
||||
* The same goes for depth textures.
|
||||
*
|
||||
* * Enabling Mipmapping:
|
||||
* This is similar to the texture parameters above. When "rtt" is specified
|
||||
* in the mode string, "mipmap" must also be specified in order to enable
|
||||
* a mipmapped pbuffer. Then, the mipmaps must be created by enabling the
|
||||
* GL_SGIS_GENERATE_MIPMAP texture parameter in the same way as above, and
|
||||
* the min filter mode must be set to a mipmap filter mode, as with any
|
||||
* mipmapped texture object.
|
||||
*
|
||||
* * Enabling Anisotropic Filtering
|
||||
* As with the texture parameters above, except as in the following code:
|
||||
* glGetFloatv(GL_MAX_TEXTURE_MAX_ANISOTROPY_EXT, max);
|
||||
* glTexParameterf(target, GL_TEXTURE_MAX_ANISOTROPY_EXT, <value < max>);
