Name

textureMode()

Description

Sets the coordinate space for texture mapping. The default mode is IMAGE, which refers to the actual coordinates of the image. NORMAL refers to a normalized space of values ranging from 0 to 1. This function only works with the P2D and P3D renderers.

With IMAGE, if an image is 100 x 200 pixels, mapping the image onto the entire size of a quad would require the points (0,0) (100, 0) (100,200) (0,200). The same mapping in NORMAL is (0,0) (1,0) (1,1) (0,1).

Examples

```
size(400, 400, P3D);
noStroke();
PImage img = loadImage("shells.jpg");
beginShape();
texture(img);
vertex(40, 80, 0, 0);
vertex(320, 20, 400, 0);
vertex(380, 360, 400, 400);
vertex(160, 380, 0, 400);
endShape();
```
```
size(400, 400, P3D);
noStroke();
PImage img = loadImage("shells.jpg");
textureMode(NORMAL);
beginShape();
texture(img);
vertex(40, 80, 0, 0);
vertex(320, 20, 1, 0);
vertex(380, 360, 1, 1);
vertex(160, 380, 0, 1);
endShape();
```
