Textured Plane

A plane showing a texture loaded from an image file.

This component is a subclass of OpenGLComponent and therefore uses the OpenGL display service.

Example Usage

A plane showing an image loaded from the file "nemo.jpeg":

PLANE = TexPlane(position=(0, 0,-6), texture="nemo.jpeg").activate()

Axon.Scheduler.scheduler.run.runThreads()

How does it work?

This component is a subclass of OpenGLComponent (for OpenGLComponent functionality see its documentation). It overrides __init__(), setup(), draw().

In setup() the method loadTexture() get called which loads the texure from the image file specified. If the image in the file has dimensions which are not equal a power of two, the texture dimensions get enlarged (this is needed because of OpenGL texturing limitations).

In draw() a simple plane is drawn whith the loaded texture on it.
