0003 SGLFW_SOPTIX_Scene_test.sh : triangulated raytrace and rasterized visualization
0004 =================================================================================
0005
0006 Assuming the scene folder exists already::
0007
0008     ~/o/sysrap/tests/SGLFW_SOPTIX_Scene_test.sh
0009
0010 As this uses GL interop it may be necessary to select the display GPU, eg with::
0011
0012     export CUDA_VISIBLE_DEVICES=1
0013
0014
0015 Bash args
0016 ------------
0017
0018 info
0019    dump vars
0020
0021 open
0022    write context file, use this to control where screenshots are copied to
0023
0024 run
0025    run executable
0026
0027 dbg
0028    run under gdb
0029
0030 close
0031    delete context file

0034 ENVVAR notes
0035 --------------
0036
0037 WH FULLSCREEN EYE LOOK UP TMIN ESCALE CAM VIZMASK
0038     view control envvars used by SGLM.h, details for some of them below
0039
0040 VIZMASK
0041     control CSGSolid to display, see SGLM::is_vizmask_set and SOPTIX_Properties::visibilityMask
0042     examples::
0043
0044          VIZMASK=0      # only global:0
0045          VIZMASK=0,1
0046          VIZMASK=t0     # mask global:0 (t0 means NOT 0)
0047          VIZMASK=t0,1   # mask global:0 and 1
0048
0049
0050 SGLFW__DEPTH
0051     enables download and saving of jpg depth maps together with ordinary screenshots
0052     see SGLFW::init_img_frame
0053
0054 SOPTIX__HANDLE
0055     selects what to include in the OptiX geometry, not the OpenGL one,
0056     so must switch to the CUDA/OptiX render with C key to see effect of changes.
0057     As solids usually much smaller than full geometry will usually need to
0058     adjust the target frame, eg with::
0059
0060         MOI=EXTENT:1000 SGLFW_SOPTIX_Scene_test.sh
0061
0062 SOPTIX_Options__LEVEL
0063     SOPTIX logging level
0064
