From f03d253f55060d3ae238e068c620d76b7dcf0ede Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Lukas=20T=C3=B6nne?= Date: Thu, 18 Sep 2014 09:24:31 +0200 Subject: Disabled the velocity filtering feature for now, since the weighting is incorrect. The voxel grid needs better tool support to make it usable, so fixing the filtering is not high priority right now. --- release/scripts/startup/bl_ui/properties_particle.py | 1 - source/blender/makesrna/intern/rna_cloth.c | 2 ++ source/blender/physics/intern/BPH_mass_spring.cpp | 2 ++ source/blender/physics/intern/hair_volume.c | 2 ++ source/blender/physics/intern/implicit.h | 2 ++ 5 files changed, 8 insertions(+), 1 deletion(-) diff --git a/release/scripts/startup/bl_ui/properties_particle.py b/release/scripts/startup/bl_ui/properties_particle.py index 5b52475218d..8afd2d02170 100644 --- a/release/scripts/startup/bl_ui/properties_particle.py +++ b/release/scripts/startup/bl_ui/properties_particle.py @@ -323,7 +323,6 @@ class PARTICLE_PT_hair_dynamics(ParticleButtonsPanel, Panel): sub.separator() sub.prop(cloth, "voxel_resolution") - sub.prop(cloth, "voxel_filter_size") col = split.column() col.label(text="Damping:") diff --git a/source/blender/makesrna/intern/rna_cloth.c b/source/blender/makesrna/intern/rna_cloth.c index eff194fcd5c..154ab7db52d 100644 --- a/source/blender/makesrna/intern/rna_cloth.c +++ b/source/blender/makesrna/intern/rna_cloth.c @@ -417,12 +417,14 @@ static void rna_def_cloth_sim_settings(BlenderRNA *brna) RNA_def_property_ui_text(prop, "Voxel Grid Resolution", "Resolution of the voxel grid for interaction effects"); RNA_def_property_update(prop, 0, "rna_cloth_update"); +#if 0 /* disabled */ prop = RNA_def_property(srna, "voxel_filter_size", PROP_INT, PROP_UNSIGNED); RNA_def_property_int_sdna(prop, NULL, "voxel_filter_size"); RNA_def_property_range(prop, 0, 8); RNA_def_property_int_default(prop, 0); RNA_def_property_ui_text(prop, "Voxel Grid Filter Size", "Number of cells to use for filtering grid velocity"); RNA_def_property_update(prop, 0, "rna_cloth_update"); +#endif /* springs */ diff --git a/source/blender/physics/intern/BPH_mass_spring.cpp b/source/blender/physics/intern/BPH_mass_spring.cpp index 4d8f853a16b..7f647d730c1 100644 --- a/source/blender/physics/intern/BPH_mass_spring.cpp +++ b/source/blender/physics/intern/BPH_mass_spring.cpp @@ -431,8 +431,10 @@ static void cloth_calc_volume_force(ClothModifierData *clmd) } BPH_hair_volume_normalize_vertex_grid(vertex_grid); +#if 0 /* apply velocity filter */ BPH_hair_volume_vertex_grid_filter_box(vertex_grid, clmd->sim_parms->voxel_filter_size); +#endif for (i = 0; i < numverts; i++) { float x[3], v[3], f[3], dfdx[3][3], dfdv[3][3]; diff --git a/source/blender/physics/intern/hair_volume.c b/source/blender/physics/intern/hair_volume.c index 7f9704af9f6..e72df493b79 100644 --- a/source/blender/physics/intern/hair_volume.c +++ b/source/blender/physics/intern/hair_volume.c @@ -295,6 +295,7 @@ void BPH_hair_volume_normalize_vertex_grid(HairVertexGrid *grid) } } +#if 0 /* XXX weighting is incorrect, disabled for now */ /* Velocity filter kernel * See http://en.wikipedia.org/wiki/Filter_%28large_eddy_simulation%29 */ @@ -363,6 +364,7 @@ void BPH_hair_volume_vertex_grid_filter_box(HairVertexGrid *grid, int kernel_siz copy_v3_v3(grid->verts[i].velocity, grid->verts[i].velocity_smooth); } } +#endif HairVertexGrid *BPH_hair_volume_create_vertex_grid(int res, const float gmin[3], const float gmax[3]) { diff --git a/source/blender/physics/intern/implicit.h b/source/blender/physics/intern/implicit.h index 2945b0787d4..7205b607f59 100644 --- a/source/blender/physics/intern/implicit.h +++ b/source/blender/physics/intern/implicit.h @@ -155,7 +155,9 @@ void BPH_hair_volume_free_vertex_grid(struct HairVertexGrid *grid); void BPH_hair_volume_add_vertex(struct HairVertexGrid *grid, const float x[3], const float v[3]); void BPH_hair_volume_normalize_vertex_grid(struct HairVertexGrid *grid); +#if 0 /* XXX weighting is incorrect, disabled for now */ void BPH_hair_volume_vertex_grid_filter_box(struct HairVertexGrid *grid, int kernel_size); +#endif void BPH_hair_volume_vertex_grid_forces(struct HairVertexGrid *grid, const float x[3], const float v[3], float smoothfac, float pressurefac, float minpressure, float f[3], float dfdx[3][3], float dfdv[3][3]); -- cgit v1.2.3
