Additional Sunflow options (tests)
Sunflow has command line options to control the rendering result without the GUI.
The goal here is to test their actions in Sweet Home 3D.

* Option:
-threads X
Allows you to force the number of threads used for rendering (BucketRenderer, MultipassRenderer).
Default value: number of available processors.

SH3D implementation:
int threads = X;
this.sunflow.parameter("threads", threads);
this.sunflow.options(SunflowAPI.DEFAULT_OPTIONS);

No major differences in rendering time if the number of virtual threads is greater than the number of actual threads available.

* Options:
-lopri
-hipri
Allows you to set the priority of the threads.
Default value: lowPriority = true.

SH3D implementation:
boolean lowPriority = true;
this.sunflow.parameter("threads.lowPriority", !lowPriority);
this.sunflow.options(SunflowAPI.DEFAULT_OPTIONS);

No major differences in rendering time.

Re: Additional Sunflow options (tests)
* Option:
-showaa
Display sampling levels per pixel for bucket renderer.
Default value: showAA = false.

SH3D implementation:
boolean showAA = false;
this.sunflow.parameter("aa.display", !showAA);
this.sunflow.options(SunflowAPI.DEFAULT_OPTIONS);

showAA = true

showAA = false

Re: Additional Sunflow options (tests)
* Options:
-quick_uvs : Renders the UVs of objects.
-quick_normals : Renders the normals of objects.
-quick_id : Renders using a unique color for each instance.
-quick_prims : Renders using a unique color for each primitive.
-quick_gray : Renders all the objects in the scene gray diffuse, overriding all shaders.
-quick_wire : Renders objects as wireframe.
-quick_ambocc X : Renders a scene in ambient occlusion mode with a certain distance (X).
Only one override shader at a time can be used.

SH3D implementation:
String shaderOverride = null; // "show_uvs","show_normals","show_instance_id","show_primitive_id","quick_gray","wireframe","ambient_occlusion"
if (shaderOverride.equals("ambient_occlusion")) {
float maxDist = 200f;
this.sunflow.parameter("maxdist", maxDist);
}
this.sunflow.shader("cmdline_override", shaderOverride);
this.sunflow.parameter("override.shader", "cmdline_override");
this.sunflow.options(SunflowAPI.DEFAULT_OPTIONS);

shaderOverride != null

Re: Additional Sunflow options (tests)
Nice renderings!

Re: Additional Sunflow options (tests)

Nice renderings!

Thank you VeroniQ!
I take the opportunity to propose a small survey.

Among the new rendering options, which ones do you find most interesting?

A: show_uvs

B: show_normals

C: show_instance_id

D: show_primitive_id

E: quick_gray

F: wireframe

G: ambient_occlusion (X)

Re: Additional Sunflow options (tests)
I like E: Quick Grey but the colored ones (especially C and D) are fun!

Posted by ndorigatti at Jun 5, 2019, 7:42:35 PM

Re: Additional Sunflow options (tests)
quick gray, wireframe and ambient occlusion (E F G)

Re: Additional Sunflow options (tests)
The additional Sunflow options plug-in will be available with the new version of the photo-video plug-in.

Hello hello community
how to install SunFlow
I would like to improve my rendering and how to use it? i have already downloaded but there is no executable file

Thank you william from Cameroon

Hi William!

You can download the precompiled version Sunflow-v0.07.2 and run the sunflow.jar file directly or sunflow.bat after editing.

You can also download the latest version Sunflow-v0.07.3 and follow the build instructions of the README file.
