i’m quite new to using rhino 5 as a visualization tool. hopefully there is someone out there helping me out with a quite standard render issue.
i just want to display a simple shadow on my floor object, but i must miss something quite simple.
My guess is the problem is video driver or configuration related.
Please go into Rhino Options - View - OpenGL and take a screenshot of the settings there.
Please return the image in a reply.
It should have the details needed to make a suggestion.
Reverse the check marks.
Check using accelerated hardware modes and uncheck the other three options.
I hope you are running a supported graphics card. If you’re not, that would explain perhaps why your options setting and not default values.
When the first option is left unchecked, then Rhino makes OpenGL calls to Windows emulation that is OpenGL version 1.1. Rhino shadows require OpenGL 2.0 and Shader 1.2
OK, that’s why the accelerated hardware was unchecked. You’re running an unrecommended Intel graphics chip. When Rhino detects the Intel chip, it disables the accelerated hardware option. This is covered in the Rhino 5 System Requirements: http://www.rhino3d.com/new/admin#system http://wiki.mcneel.com/rhino/rhino5videocards
It looks like you chose a computer for Rhino without checking what Rhino’s requirements were.
If the shadow feature is important for you, you’ll need to get a different laptop computer with an AMD or Nvidia graphics card that supports the OpenGL and Shader requirements of Rhino V5. If you’re running a desktop, then you can probably install a supported graphics card.
Sorry.
If it’s still new, maybe you can trade it for a 15" model with the second graphics chip.
Many of the techs here in Seattle are running 15" MBP Retinas.
