This is a complete noob question so please bare with me.
Im trying to write a script that uses Vray to render a user selected region to the pictureviewer. Its supposed to work like the built in C4d Render region command just that it render the area to the picture viewer instead. I stumble upon a couple of problems.
- How can i get the mouse coordinates (user drags out a rectangle) from the viewport.
- How can i convert the above coordinates to percentage values of the viewport size.
I have figured out how to set the region in the Render settings, but im completely lost on the mouse/viewport thing
I really wish the SDK had more meaningful examples. This would make it so much easier for noobs like myself to learn faster.
from c4d import documents, bitmaps, gui
#Welcome to the world of Python
doc = documents.GetActiveDocument()
rd = doc.GetActiveRenderData()
post = rd.GetFirstVideoPost()
if post == None:
if post.GetType() == 1019782: ## if Video Post Effect is V-Ray Bridge
vray = post
post = None ## changes post object to none so the loop is broken
post = post.GetNext() ## Try the next Post-Effect
vray[c4d.VP_VRAYBRIDGE_REGIONON] = True # Turns on Render region in the Vray effect
vray[c4d.VP_VRAYBRIDGE_REGIONRENDER_X1] = 0.1 #Sets the values for the region in the Vray effect
vray[c4d.VP_VRAYBRIDGE_REGIONRENDER_Y1] = 0.1
vray[c4d.VP_VRAYBRIDGE_REGIONRENDER_X2] = 0.9
vray[c4d.VP_VRAYBRIDGE_REGIONRENDER_Y2] = 0.9
Any help appreciated
