Spheric skydome for panorama

Hi,

I am wondering if anyone as tried to use a spheric environmental map instead of the cubic one refered in the help.

Thanks,
Marco Simões

Vizard comes with a few models that use a panoramic 2d image to create a sky dome, instead of a cube map. Have a look at the sky_day.osgb and sky_night.osgb models in the resources folder. Both those models were created with 3ds Max.

Hi farshizzo,

Thank you a lot for your reply!

I looked into those models, but still I'm having troubles achieving my goal.

I cannot import osgb files into 3ds max (I think...) so I tried to do some attempts to texture over those model directly in vizard.

I could not get the result I was hoping for...

I'm attaching one example of panorama I'm trying to use. Could you give me some feedback on how to proceed?

Thank you a lot!

You will need to create your own model with the proper UV coordinates.

The sample image you provided looks like it can be applied to a standard cylinder. Try the following code:

Code:

import viz

import vizshape



viz.go()

viz.fov(60)



panorama = viz.add('panorama.jpg')

cyl = vizshape.addCylinder(radius=100,height=200,slices=100,flipFaces=True,top=False,bottom=False)

cyl.texture(panorama)

viz.link(viz.MainView,cyl,mask=viz.LINK_POS)
