Code: Select all

love.graphics.setMeshCullMode("back")
model:draw()	--drawn with back culling

love.graphics.setMeshCullMode("front")
model2:draw()	--drawn with front culling

Why didn't I think of that? Does it have any sort of impact on performance?

A model would have multiple meshes as OBJ+MTL can define multiple materials for multiple 'objects' within the file. This means g3d would have to implement a material system to support it - when g3d aim is meant to keep simple so people can easily customize it with little overhead. You could fork it and add such a system in if you want - MTL files are human readable similar to OBJ and you could make the addition in a couple days of works.

Edit: g3d also supports colours within meshes, but not via the obj reader. `VertexColor` can be found as the 4th attribute to the vertex layout (9th index of the vertex (lua arrays)).

(I only want the face color definitions, not trying to replicate stuff like shiny metal or rough brick textures or whatever) I could probably try and figure it out myself.

Tilt it on the X (Looking up and down) axis. But how if possible, do you tilt it on the Y (Forward) axis? Is this possible officially? Or can it be easily implemented? I guess it would also be referred to as rolling the camera.

g3d.camera.up = {some vector here}
g3d.camera.updateViewMatrix()

Something like:

Code: Select all

g3d.camera.up = {some vector here}
g3d.camera.updateViewMatrix()
