FrameBufferProperties
from panda3d.core import FrameBufferProperties
- class FrameBufferProperties
Bases:
A container for the various kinds of properties we might ask to have on a graphics frameBuffer before we create a GSG.
Inheritance diagram
- __eq__(other: FrameBufferProperties) bool
- __init__()
- __init__(param0: FrameBufferProperties)
- __ne__(other: FrameBufferProperties) bool
- addProperties(other: FrameBufferProperties)
Sets any properties that are explicitly specified in other on this object. Leaves other properties unchanged.
- clear()
Unsets all properties that have been specified so far, and resets the
FrameBufferProperties
structure to its initial empty state.
- property color_bits int
Getter Setter
Sets the number of requested color bits as a single number that represents the sum of the individual numbers of red, green and blue bits. Panda won’t care how the individual bits are divided up.

setRgbaBits()
, which allows you to specify requirements for the individual components.
- property coverage_samples int
If coverage samples are specified, and there is hardware support, we use coverage multisampling. multisampling
- property depth_bits int

- getCoverageSamples() int
If coverage samples are specified, and there is hardware support, we use coverage multisampling.
- static getDefault() FrameBufferProperties
Returns a
FrameBufferProperties
structure with all of the default values filled in according to the user’s config file.
- getQuality(reqs: FrameBufferProperties) int
Assumes that these properties are a description of a window.
Measures how well this window satisfies a specified set of requirements. A higher quality number means that more requirements were satisfied. A quality of zero means that the window is unsuitable.
The routine deducts a lot if the window fails to provide a requested feature. It deducts less if the window provides a feature, but at a degraded level of functionality (ie, the user asks for rgba8, color, but the window only provides rgba4). The routine also deducts a small amount for unnecessary features. For example, if the window has an accumulation buffer when one is not requested will reduce quality slightly. Maximum quality is obtained when the window exactly matches the request.
If you want to know whether the window satisfies all of the requirements, use the “subsumes” function.
- isBasic() bool
Returns true if the properties are extremely basic. The following count as basic: rgb or rgba, depth. If anything else is specified, the properties are non-basic.
- setAllSpecified()
Marks all bits as having been specified.
- setColorBits(n: int)
Sets the number of requested color bits as a single number that represents the sum of the individual numbers of red, green and blue bits. Panda won’t care how the individual bits are divided up.

, which allows you to specify requirements for the individual components.
- setCoverageSamples(n: int)
If coverage samples are specified, and there is hardware support, we use coverage multisampling
- setOneBitPerChannel()
If any of the depth, color, alpha, accum, or stencil properties is set to more than one, then they are reduced to one.
- setRgbaBits(r: int, g: int, b: int, a: int)
Convenience method for setting the red, green, blue and alpha bits in one go.
- setupColorTexture(tex: Texture) bool
Sets the texture up for render-to-texture matching these framebuffer properties.
Returns true if there was a format that had enough bits, false otherwise. Of course, this is no guarantee that a particular graphics back-end supports rendering to textures of that format.
- setupDepthTexture(tex: Texture) bool
Sets the texture up for render-to-texture matching these framebuffer properties.
Returns true if there was a format that had enough bits, false otherwise. Of course, this is no guarantee that a particular graphics back-end supports rendering to textures of that format.
- subsumes(other: FrameBufferProperties) bool
Returns true if this set of properties makes strictly greater or equal demands of the framebuffer than the other set of framebuffer properties.
- verifyHardwareSoftware(props: FrameBufferProperties, renderer: str) bool
Validates that the properties represent the desired kind of renderer (hardware or software). If not, prints out an error message and returns false.
