How to display the texture of 3Dmodel? about augmented-reality HOT 2 CLOSED

Hi @Allfu , glad you like it!

Current Status

As you can see here

if color is False, which it is by default, I am using a single color to render the model, ignoring whatever colors have been defined in the model file.

The default color used to render the model is defined here:

Render Model with colors

If you only want to render the model with colors - assuming they have been defined in the .obj file - and not textures, you should call the render function with the last parameter set to True:

The call to the render function is done here:

an example of a model with colors is the Pirate Ship (https://github.com/juangallostra/augmented-reality/blob/master/models/pirate-ship-fat.obj). Colors are defined in hex format:

To load colors you should also uncomment the lines:

See below an example result of the Pirate Ship and Fox colored models:

The second one is taken from piotrekk94's fork: https://github.com/piotrekk94/tx2-ar, which has some other improvements.

Render model with textures

If what you want is to display a texture for the model, then yes, you should combine the OBJ model with the MTL file.

The code I am using to load OBJ models is based on this one: https://www.pygame.org/wiki/OBJFileLoader
As you can see in the link, there is a second class I removed which loads MTL files. In addition to that, lines

should be uncommented. The problem with textures is that you will then need OpenGL (or something similar) to render the model, which was work I didn't want to do at the time. It is possible, however, to do so.
