Re: Simulate sun position and lights/shadows

I never tried using multiple shaders per object. I'll have to test that. Thank you for the idea! smile

Just as long as you don't use Phong C1 biggrin even with Importance sampling turned on it still looks like a squashed ball compared to Uber shader.

Can't wait to test this and see the new render results!

Thanks,

Re: Simulate sun position and lights/shadows

Hi Emmanuel,

Firstly thank you for the interesting link on caustics.

Now that advanced rendering plug-in version 1.2 has been thoroughly tested (oh! Also not forgetting the BasicPlusExtraLights.sh3f package of course! wink He he) will you be updating the front page so people who don't visit the forum can know about them? Many may still be using version 1.1 and not even know about 1.2.

Re: Simulate sun position and lights/shadows

To db4tech and other interested testers,
Here are two temporary plug-ins that will let you test SunFlow's Uber and Phong Shader:
http://www.sweethome3d.com/plugins/AdvancedRendering-PhongShader-1.3.sh3p
http://www.sweethome3d.com/plugins/AdvancedRendering-UberShader-1.3.sh3p
These plug-ins create two new menu items in Tools menu, so you can distinguish them from each other.

To change the shininess of an object, you'll have to play with the shininess value and the specular color stored in the Ns et Ks parameters of its MTL file. If you're patient enough, try to render different existing homes in the galeries, and give us your opinion.

Please don't link these files in an other document, because I'll probably delete them once we decide which track to follow.

[Note]
2010/05/26: These two plug-ins were updated to support models at DAE/Collada format.

Re: Simulate sun position and lights/shadows

I've still not managed to get a slightly shiny floor yet.

Here is how the same scene renders with the 3 different shaders.

For reference. Normal Advanced photo render version 1.2 (Shiny shader)


Phong shader


Uber shader


Uber shader seems to be badly affected by the room ceiling light, the problem disappears if the ceiling light is turned off (Emmanuel is this with Importance sampling turned on?) Phong shader is slightly affected by the ceiling light.

Here are my findings so far (apart from the floor) with Phong and Uber shaders all items that should be reflective are even more reflective, notice the knobs on the unit and strangely the curtains?

Apart from the obvious ceiling light issues, both Phong and Uber shaders render all lights used in a scene with a brighter intensity than Shiny shader, Phong slightly brighter and Uber very brightly, notice the window frame and chair reflecting brightly the lights illuminating the scene placed behind the virtual visitor.

Render speeds:
Shiny shader is the fastest
Phong and Uber about the same, sometimes Phong was faster, other times Uber was, it was too close to call without carrying out some accurately timed renders.

More tests to follow.

db4tech:

Could you make your file available? I would like to do some tests on exactly the same file as you are using.

Re: Simulate sun position and lights/shadows

Hi Hans,

Yes of course, it isn't a fully designed house or room, just a quick purposely built model for this test.
