#OpenGL .obj Viewer#
A simple OpenGL viewer for .obj files. I wrote it for OpenGL 2.1 (with VAO and shaders) so that it runs reliably on lots of machines. I might extend or fork this to do more interesting things.
##Limitations##
.obj files must have:
- points
- texture coordinates
- normals
and must be triangulated
MTL files are not supported.
##Instructions##
If you run the viewer with no parameters it uses a default mesh and texture.
./viewer
You can specify:
-
.obj file to load
-o mymesh.obj
-
texture to load
-tex mytexture.png
-
shaders to load
-vs myshader.vert -fs myshader.frag
-
scale to apply uniformly (if the mesh is too big to fit in view)
-sca 0.5
-
translation XYZ to apply (to centre mesh in view)
-tra 0.0 -1.0 0.0
##Keys##
- F11 - screenshot
- N - toggle visualisation of normals
- P - fill/wireframe/points
##To Do##
- Support meshes with different components
- Display my .apg format meshes as well
