TextureContext¶

class TextureContext¶

Bases: BufferContext, AdaptiveLruPage

This 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.

static TextureContext.get_class_type()¶

TextureContext.get_image_modified()¶: Returns a sequence number which is guaranteed to change at least every time the texture image data (including mipmap levels) are modified.

TextureContext.get_image_modified_pages()¶: Returns a SparseArray indicating which pages of the texture have been modified since the last call to mark_loaded().

TextureContext.get_native_buffer_id()¶

//virtual uint64_t get_native_id() const;

/**

Similar to get_native_id, 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.

TextureContext.get_properties_modified()¶: Returns a sequence number which is guaranteed to change at least every time the texture properties (unrelated to the image) are modified.

TextureContext.get_texture()¶: Returns the pointer to the associated Texture object.

TextureContext.get_view()¶: Deprecated: since 1.11.0: always returns 0.

TextureContext.get_view_modified_pages()¶: Returns a SparseArray indicating which pages of the texture have been modified since the last call to mark_loaded().

TextureContext.was_image_modified()¶: Returns true if the texture image has been modified since the last time mark_loaded() was called.

TextureContext.was_image_page_modified()¶: Returns true if the given page of the texture image has been modified since the last time mark_loaded() was called.

TextureContext.was_modified()¶: Returns true if the texture properties or image have been modified since the last time mark_loaded() was called.

TextureContext.was_properties_modified()¶: Returns true if the texture properties (unrelated to the image) have been modified since the last time mark_loaded() was called.
