Introduce pixel_size_to_world_size function for accurate world size calculation based on pixel size. - Update BillboardPointRenderer to use fixed pixel size for point handles, improving consistency in rendering. - Modify RenderingConstants to define POINT_HANDLE_PIXEL_SIZE for better control over point size. - Adjust draw_billboard_quad_3d calls to utilize calculated world size, ensuring proper scaling in various view contexts. - Refine geometry regeneration logic to account for viewport size changes, enhancing performance and visual fidelity. --- model/vulkan_compat.py | 23 +++++++++-------------- utilities/constants.py | 6 +++--- utilities/draw.py | 35 +++++++++++++++++++++++++++++++++++ 3 files changed, 47 insertions(+), 17 deletions(-) diff --git a/model/vulkan_compat.py b/model/vulkan_compat.py index 410e1a4b..143825d3 100644 --- a/model/vulkan_compat.py +++ b/model/vulkan_compat.py @@ -12,7 +12,7 @@ from mathutils import Vector from ..utilities.constants import RenderingConstants -from ..utilities.draw import draw_billboard_quad_3d +from ..utilities.draw import draw_billboard_quad_3d, pixel_size_to_world_size from ..utilities.gpu_manager import ShaderManager logger = logging.getLogger(__name__) @@ -66,9 +66,11 @@ def _ensure_billboard_geometry(self, context): if not getattr(self, '_needs_billboard_update', True): return -
