Hi, I've finally implemented the feature " <invisible_to_camera>true</invisible_to_camera> " present in Indigo 3.6.22 in My Application. I was waiting since 2008.... :lol: This is the first Test The image "No walls and ceiling" has only two walls and one floor (not using "invisible_to_camera") The i...

BRDF Explorer is an application that allows the development and analysis of bidirectional reflectance distribution functions (BRDFs). It can load and plot analytic BRDF functions (coded as functions in OpenGL's GLSL shader language), measured material data from the MERL database, and anisotropic mea...

Indigo capable of calculating illuminance plus BDRF materials plus IES lights...

A complete new market...



[EDIT]

P.S. Here you will find more BRDF Materials and the CPP source code to read them...

Or you can use the Disney's BRDF Explorer, see my Post here...

Do you mean something like this... The old Lightscape 3.2 Classrom

Computer scientists develop new model to simulate cloth on a computer with unprecedented accuracy. Abstract: This paper introduces a simple shading model for cloth. The model can simulate both the anisotropic highlights on cloth as well as the complex color shifts seen in cloth made of different col...

Sorry guys: how is the "new" alpha background rendering feature supposed to work? I have some issue trying to use that.. Its a checkbox in the Render Settings and instead of rendering Indigo Sky or background HDRI you get transparency at that area. Also transparency behind glass like glass windows ...

Added invisible to camera option to models.

Could you please suggest the igs-code to enable this option?

Thank you very much.

A.Delle

Ooops I miss it

Edit: Which is the minimum Indigo version that supports them? E.g. starting from version.... (to configure my exporter)

Bye

Ono I have the source code to complete process IES Lights, asymmetric light too :wink: It even manages light with partial angles (eg. 0,45,90 or 0 to 90 and 270 to 360), it calculates missing values using Splines. At the end of the processing it return the complete angles (0 to 360) If you send me a...

Great!

Thank you

culling on versus culling off on section planes I've been waiting for this since a long time... Can you suggest the syntax for my exporter? Thank you! <section_plane> <point>3 0 0</point> <normal>-1 0 0</normal> <cull_geometry>false</cull_geometry> </section_plane> Thank you, Do you think that, in ...

Thank you!

Hi Delle, Good point, I hadn't thought of that. There will probably be a restriction though that the material on each side can't transmit light. This is so the transmitted component is the same in both directions (front -> back and back -> front). So null materials won't be allowed. I see, do you t...

Hi, great news! One question: One of the two materials can be "an invisible material"? If so, you have just created a triangle visible only from one side! If so, you have just solved this problem: to create a wall that is "opaque" internally (it reflects back the light) but invisible from the outsid...

Delle is writing an exporter (for his own arch application iirc), what he is asking for are technical details :) Here's what we got: You can add a section plane to a scene like so: <section_plane> <point>3 0 0</point> <normal>-1 0 0</normal> <enabled>true</enabled> </section_plane> Only geometry on...
