Re: Additional Sunflow options (tests)
@ enkonyito

Maybe this is not the right thread to discuss this, but I'm somewhat puzzled by the way Sunflow handles shininess.
It's like shininess is either on or off, with nothing in between.
I have done several tests on this, and I'm really wondering if the shininess slider has any function at all.
Is this just a result of the limitations imposed by SH3D, or is this a real Sunflow limitation?

It's like shininess is either on or off, with nothing in between.

In the Modify furniture panel, Matt=0 and Shiny=0.5.
In the Furniture materials panel, Matt=0 and Shiny=1. The Java 3D preview lets you see the difference in shininess.

When rendering, Sunflow applies a shader to the material that "changes" the shininess. (see pages 14 to 23 of Sunflow Wiki PDF)

Is this just a result of the limitations imposed by SH3D, or is this a real Sunflow limitation?

As Puybaret had told me : "There's no limitation".
Sunflow's standard configuration in Sweet Home 3D is based on several tests performed in 2010 (Test 1, Test 2).

Re: Additional Sunflow options (tests)
* Option:
-bucket X Y
Changes the default bucket size to n pixels and the default order (BucketRenderer, MultipassRenderer).
Sunflow default value: bucketSize = 32, bucketOrder = hilbert.
SH3D default value: bucketSize = 64, bucketOrder = spiral.

SH3D implementation:
int bucketSize = 16; // min = 16, max = 512
this.sunflow.parameter("bucket.size", bucketSize);
String bucketOrder = "spiral"; // hilbert, spiral, column, row, diagonal or random can be reversed
this.sunflow.parameter("bucket.order", bucketOrder);
this.sunflow.options(SunflowAPI.DEFAULT_OPTIONS);

Re: Additional Sunflow options (tests)
These options will no longer be managed in the next version of the photo-video rendering plug-in.
