#USER view, camera sel
2 messages in this thread
I asked this question before, but now that I have a little more information,
I'll try again. I would like to set the USER view from within a PXP. I have
looked at "VIEW.C, VIEW_I.PXP" by Gus J Grubba and this shows how to setup your
own view. From working with CAD I already have my matrix routines developed
and debuged, so the math is no problem, and I could replace the USER view with
my own imitation. But, once my IPAS was terminated the USER view would remain
unchanged. I have tried modifing the Viewport structure, and then redrawing
the viewport, but this does nothing. You mentioned last time about using the
File Toolkit, could you elaborate? Right now I have it using a camera view, and
with our 3D input device, you can fly around your mesh object in almost
real-time; but since you cannot edit in a camera view, it doesn't help me much.
Which brings up another question. How can I select cameras and lights in a
PXP. EXP_PICK_OBJECT works great for mesh objects, but does nothing for cameras
and lights, and I can't seem to find anything else that works in a PXP.
KXP_PICK_NODE looks like it would be perfect, but it doesn't seem to work in a
PXP.
Any help or suggestions would be greatly appreciated…

IPAS4 will allow you to do_3ds_save.
The 3DS File toolkit has a GetViewport3DS and a PutViewport3DS functions and
also there is a data structure called UserView3ds containing the center, zoom,
horang, verang. You could change these values, and use IPAS4 to do_3ds_load the
modified *.3ds file prior to exiting.

Have you looked at the possibilities of using gfx_camera_at and gfx_light_at,
etc.. as an avenue? Also, slightly relevant here.. have you seen..?
