Terrain to Mesh3D with Toxiclibs

RogerHolloway

Hi all,

I extracted a part of this code: http://www.openprocessing.org/sketch/8880 I just want to get the terrain with peasycam. Somehow, I get the following error: "cannot convert from Mesh3D to TriangleMesh". I checked the toxiclibs references and everything seems ok. I don't know what I did wrong.

Thank you for your help,

Roger

Hints (error message, javadocs) were pretty clear. Your object type is a 'TriangleMesh' and you are getting a 'Mesh3D'. These do not match. So either change your object type (line 19 to Mesh3D mesh;) or change what your are getting (line 36 to mesh = (TriangleMesh) terrain.toMesh(0);).

Also, since this question requires a library, it should be in the library questions section. Moved. See: http://forum.processing.org/two/discussion/8043/how-to-choose-a-category-in-this-forum
