* raylib [models] example - loading iqm
|
|
*
|
|
* Example complexity rating: [★★☆☆] 2/4
|
|
*
|
|
* Example originally created with raylib 2.5, last time updated with raylib 3.5
|
|
*
|
|
* Example contributed by Culacant (@culacant) and reviewed by Ramon Santamaria (@raysan5)
|
|
*
|
|
* NOTES: To export an IQM model from blender, make sure it is not posed, the vertices need
|
|
* to be in the same position as they would be in edit mode and the scale of the models is
|
|
* set to 0; scaling can be set from the export menu
|
|

* Example licensed under an unmodified zlib/libpng license, which is an OSI-certified,
