panda3d.core.TextureContext¶

class
TextureContext¶ Bases:
BufferContext,AdaptiveLruPageThis is a special class object that holds all the information returned by a particular GSG to indicate the texture’s internal context identifier.
Textures typically have an immediate-mode and a retained-mode operation. When using textures in retained-mode (in response to
Texture.prepare()), the GSG will create some internal handle for the texture and store it here. The texture stores all of these handles internally.Inheritance diagram

getClassType() → TypeHandle¶ - Return type
-
getImageModified() → UpdateSeq¶ Returns a sequence number which is guaranteed to change at least every time the texture image data (including mipmap levels) are modified.
- Return type
-
getNativeBufferId() → uint64_t¶ Similar to
getNativeId(), but some implementations use a separate identifier for the buffer object associated with buffer textures. Returns 0 if the underlying implementation does not support this, or if this is not a buffer texture.- Return type
uint64_t
-
getNativeId() → uint64_t¶ Returns an implementation-defined handle or pointer that can be used to interface directly with the underlying API. Returns 0 if the underlying implementation does not support this.
- Return type
uint64_t
-
getPropertiesModified() → UpdateSeq¶ Returns a sequence number which is guaranteed to change at least every time the texture properties (unrelated to the image) are modified.
- Return type
-
getSimpleImageModified() → UpdateSeq¶ Returns a sequence number which is guaranteed to change at least every time the texture’s “simple” image data is modified.
- Return type
-
getView() → int¶ Returns the specific view of a multiview texture this context represents. In the usual case, with a non-multiview texture, this will be 0.
-
wasImageModified() → bool¶ Returns true if the texture image has been modified since the last time mark_loaded() was called.
-
wasModified() → bool¶ Returns true if the texture properties or image have been modified since the last time mark_loaded() was called.
-
wasPropertiesModified() → bool¶ Returns true if the texture properties (unrelated to the image) have been modified since the last time mark_loaded() was called.
-
wasSimpleImageModified() → bool¶ Returns true if the texture’s “simple” image has been modified since the last time mark_simple_loaded() was called.
