5 years agoRedesign file writing in the Blender exporter
Mikko Rasa [Wed, 15 May 2019 21:42:03 +0000 (00:42 +0300)]
Redesign file writing in the Blender exporter

Instead of writing statements directly to the file as string fragments,
construct an in-memory representation of the exported data first.  This
allows it to be manipulated and combined easier.

Temporarily remove the material texture feature from Blender exporter

It gets in the way of other improvements and will be replaced by a
similar yet different feature later.

5 years agoOnly use texunit zero in exporter-generated techniques
Mikko Rasa [Sun, 12 May 2019 06:59:53 +0000 (09:59 +0300)]
Only use texunit zero in exporter-generated techniques

It does not make much sense to use anything else without shaders, and
accessing the mesh to find out unit numbers is getting in the way of
some other changes.

Fix some errors in the triangulation algorithm

Normals were reversed and edge links were not being updated properly.

5 years agoRewrite triangle strip generation in the Blender exporter
Mikko Rasa [Sun, 5 May 2019 13:54:37 +0000 (16:54 +0300)]
Rewrite triangle strip generation in the Blender exporter

The old algorithm had many of the right ideas but was too clever by half
and consequently very complex.  Use a simpler score-based algorithm
developed by Tom Forsyth.  Also reorder vertices to make memory accesses
to them occur in a more linear fashion.

Options related to cache optimization were removed since there's
no good reason not to optimize.

5 years agoExplicitly triangulate faces in the Blender exporter
Mikko Rasa [Sat, 4 May 2019 23:16:22 +0000 (02:16 +0300)]
Explicitly triangulate faces in the Blender exporter

Previously they were implicitly triangulated during strip generation,
with the idea that it would be more flexible.  However I have some
doubts of its benefits and existing strip generation algorithms tend
to deal exclusively in triangles.

Simplify the vertex splitting algorithm

5 years agoMake the edge map transient
Mikko Rasa [Sat, 4 May 2019 20:11:47 +0000 (23:11 +0300)]
Make the edge map transient

It's only actually used to associate edges with faces so it's simpler if
it doesn't need to be maintained in other functions.

Improve progress reporting in the Blender exporter

Pushing and popping tasks now makes more sense.  The Progress object
always exists but it's possible to suppress reporting (see 9b57666) by
giving it a falsy context.  Progress reporting has been added to a few
places that previously lacked it.

Major rework of mesh handling in Blender exporter

All of the preprocessing has been moved out of the MeshExporter class and

classes to use meshes.
