From be787bc40ba0bb9c7bb622b6172f24b8b8119ec6 Mon Sep 17 00:00:00 2001 From: Mikko Rasa Date: Tue, 4 Jun 2019 13:39:27 +0300 Subject: [PATCH] Export world transforms for scene objects The location, rotation and scale properties contain transform components relative to the somewhat arbitrary basis matrix. Obtain the values from the world matrix instead. A drawback is that nonuniform or negative scaling can produce inconsistent results. --- blender/io_mspgl/export_scene.py | 27 ++++++++++++++------------- 1 file changed, 14 insertions(+), 13 deletions(-) diff --git a/blender/io_mspgl/export_scene.py b/blender/io_mspgl/export_scene.py index c66feed7..abdd61b0 100644 --- a/blender/io_mspgl/export_scene.py +++ b/blender/io_mspgl/export_scene.py @@ -110,21 +110,22 @@ class SceneExporter: for o in objs: obj_res = resources[prototypes[o.name].name+".object"] st = scene_res.create_reference_statement("object", obj_res, o.name) - # XXX Parent relationships screw up the location and rotation + ss = Statement("transform") - ss.sub.append(Statement("position", o.location[0], o.location[1], o.location[2])) - if o.rotation_mode=="AXIS_ANGLE": - angle = o.rotation_axis_angle[0] - axis = o.rotation_axis_angle[1:] + + loc = o.matrix_world.to_translation() + ss.sub.append(Statement("position", *tuple(loc))) + + quat = o.matrix_world.to_quaternion() + if o.rotation_mode in ('XYZ', 'XZY', 'YXZ', 'YZX', 'ZXY', 'ZYX'): + angles = [a*180/math.pi for a in quat.to_euler()] + ss.sub.append(Statement("euler", *angles)); else: - if o.rotation_mode=="QUATERNION": - q = o.rotation_quaternion - else: - q = o.rotation_euler.to_quaternion() - angle = q.angle - axis = q.axis - ss.sub.append(Statement("rotation", angle*180/math.pi, axis[0], axis[1], axis[2])) - ss.sub.append(Statement("scale", o.scale[0], o.scale[1], o.scale[2])) + ss.sub.append(Statement("rotation", quat.angle*180/math.pi, *tuple(quat.axis))) + + scale = o.matrix_world.to_scale() + ss.sub.append(Statement("scale", *tuple(scale))) + st.sub.append(ss) scene_res.statements.append(st) -- 2.43.0
