Detailed Description¶
- class PySide2.Qt3DRender.Qt3DRender.QTextureLoader([parent=None])¶
- param parent:
Constructs a new
QTextureLoader
instance withparent
as parent.Note that by default, if not contradicted by the file metadata, the loaded texture will have the following properties set: -
wrapMode
set to Repeat -minificationFilter
set toLinearMipMapLinear
-magnificationFilter
set to Linear -generateMipMaps
set to true -maximumAnisotropy
set to 16.0f - target set toTargetAutomatic
- PySide2.Qt3DRender.Qt3DRender.QTextureLoader.isMirrored()¶
- Return type:
bool
This property specifies whether the texture should be mirrored when loaded. This is a convenience to avoid having to manipulate images to match the origin of the texture coordinates used by the rendering API. By default this property is set to true. This has no effect when using GPU compressed texture formats.
Warning
This property results in a performance price payed at runtime when loading uncompressed or CPU compressed image formats such as PNG. To avoid this performance price it is better to set this property to false and load texture assets that have been pre-mirrored.
Note
OpenGL specifies the origin of texture coordinates from the lower left hand corner whereas uses the the upper left hand corner.
Note
When using cube map texture you’ll probably want mirroring disabled as the cube map sampler takes a direction rather than regular texture coordinates.
