Is anybody working on a D-based really fast OpenGL-based visualization
engine that supports tessellation of 2d primitives on the GPU?
For instance, if I want to animate a huge amount of circles (in a
2d-graph) and I would like to only have to send an array of centers and
radiuses and optionally colors, and transparencies to the GPU and then
have the circles tessellated and rasterized there.
I need this for visualizing and animating huge graphs (potentially
millions of nodes) using the powers present in modern day GPUs.
I'm interested in both pure-D implementations and wrappers over
open-source C/C++ based implementations supported by Linux.
Does a Vulkan-based implementation in D provide any benefits with
regards to CPU-to-GPU-data-transfer and on-GPU-tesselation?
I also need an engine to draw 2d (and 3d later) primitives like you've
described above. I have a couple of unfinished attempts to make
something like it. My specific is ability to inspect the data using some
treeview widget. I considered GTK and Qt (both pure Qt and Qml) and they
were too complex to make such user interface. The most suitable variant
for me was dear imgui, but now I'm replacing it by nuklear. Generally I
have no complete solution to the problem, but I'd like to join efforts
to create it.
