class
GraphicsStateGuardian¶ Bases:
GraphicsStateGuardianBaseEncapsulates all the communication with a particular instance of a given rendering backend. Tries to guarantee that redundant state-change requests are not issued (hence “state guardian”).
There will be one of these objects for each different graphics context active in the system.
Inheritance diagram
-
releaseAll() → None¶ Releases all prepared objects.
-
releaseAllTextures() → int¶ Frees the resources for all textures associated with this GSG.
-
releaseAllSamplers() → int¶ Frees the resources for all samplers associated with this GSG.
-
releaseAllGeoms() → int¶ Frees the resources for all geoms associated with this GSG.
-
releaseAllVertexBuffers() → int¶ Frees the resources for all vertex buffers associated with this GSG.
-
releaseAllIndexBuffers() → int¶ Frees the resources for all index buffers associated with this GSG.
-
releaseAllShaderBuffers() → int¶ Frees the resources for all index buffers associated with this GSG.
-
setActive(active: bool) → None¶ Sets the active flag associated with the GraphicsStateGuardian. If the GraphicsStateGuardian is marked inactive, nothing is rendered. This is not normally turned off unless there is a problem with the rendering detected at a low level.
-
isActive() → bool¶ Returns the active flag associated with the GraphicsStateGuardian.
-
isValid() → bool¶ Returns true if the GSG has been correctly initialized within a graphics context, false if there has been some problem or it hasn’t been initialized yet.
-
needsReset() → bool¶ Returns true if the gsg is marked as needing a reset.
-
setIncompleteRender(incomplete_render: bool) → None¶ Sets the incomplete_render flag. When this is true, the frame will be rendered even if some of the geometry or textures in the scene are not available (e.g. they have been temporarily paged out). When this is false, the frame will be held up while this data is reloaded.
Setting this true allows for a smoother frame rate, but occasionally parts of the frame will be invisible or missing (they will generally come in within a second or two). Setting this false guarantees that every frame will be complete, but may cause more chugs as things are loaded up at runtime.
You may want to set this false during loading screens, to guarantee that all of your assets are available by the time you take the loading screen down.
This flag may also be set individually on each DisplayRegion. It will be considered true for a given DisplayRegion only if it is true on both the GSG and on the DisplayRegion.
-
setLoader(loader: Loader) → None¶ Sets the Loader object that will be used by this GSG to load textures when necessary, if
getIncompleteRender()is true.

The value returned may not be meaningful until after the graphics context has been fully created (e.g. the window has been opened).
-
getMaxVertexTransforms() → int¶ Returns the maximum number of transform matrices that may be simultaneously used to transform any one vertex by the graphics hardware. If this number is 0, then the hardware (or the graphics backend) doesn’t support soft- skinned vertices (in which case Panda will animate the vertices in software).
The value returned may not be meaningful until after the graphics context has been fully created (e.g. the window has been opened).
-
getMaxVertexTransformIndices() → int¶ Returns the maximum number of transforms there may be in a single TransformTable for this graphics hardware. If this number is 0 (but get_max_transforms() is nonzero), then the graphics hardware (or API) doesn’t support indexed transforms, but can support direct transform references.
The value returned may not be meaningful until after the graphics context has been fully created (e.g. the window has been opened).
-
getCopyTextureInverted() → bool¶ Returns true if this particular GSG has the property that any framebuffer- to-texture copy results in a texture that is upside-down and backwards from Panda’s usual convention; that is, it copies into a texture from the bottom up instead of from the top down.

-
getSupportsOcclusionQuery() → bool¶ Returns true if this GSG supports an occlusion query. If this is true, then begin_occlusion_query() and end_occlusion_query() may be called to bracket a sequence of draw_triangles() (or whatever) calls to measure pixels that pass the depth test.

The value returned may not be meaningful until after the graphics context has been fully created (e.g. the window has been opened).
-
getMaximumSimultaneousRenderTargets() → int¶ Deprecated. Use
getMaxColorTargets()instead, which returns the exact same value.
-
