is Reflection Pass hooked up yet?

jbshorty — Fri, 26 Sep 2008 14:26:40 GMT

It seems when i try to use Render Pass for "reflection only", I only get an image of the background environment and my objects are not rendered at all. Is this function hooked up yet? jonah

Who knows a tutorial to produce caustic like the image attached???

what parameter we should match for this??

To much dynamic in rendered animations

trojax — Wed, 03 Feb 2010 14:00:35 GMT

Dear MCNeel Team,

I've got some really serious problem, I can't solve on myself.

At first a short description of my work with Rhino:

I'm using Brazil/Rhino for Head-Up Display simulations for cars. For this kind of simulation, the camera is looking from the virtual cockpit of the car to the windshield. The Head-Up-Unit is located in the dashboard and consitsts of a small display (which I modelled with the brightness material and a bitmap texture) and a concave mirror that reflects the display on the windshield. the driver sees a reflection of the display on the windshiel and recognizes it as lying about 1.5 meters in front of the car. During the simulation, I'm rendering 2 animations in a 65 mm "Eye-to-eye-distance" for 3D animation with each about 400 frames lying equidistant on a "headcurve" which simulates the head-motion of a driver.

Now my problem is the following:

When the virtual head moves from left to right, the "virtual picture" in front of the car moves very much. Further, there is a big difference between left and right eye.

In the past, such simulations were done with the tool "Zemax", the results are lying very close to reality, verificated with real test. In teh Brazil renderings, the difference between left and right eye as well als the dynamic in the virtual picture is significatly higher, which means the results are not reliable for me.

I already tryid to use a finer polygon-mesh as well as to rebuild all surfaces of mirrors and the windshield, but got no differences.

Do you have any idea what could cause this and how I could get the problem solved?

Thank you very much for your answer!

Black intersections!

stuzzzzie — Tue, 02 Feb 2010 17:37:47 GMT

When I render my model with intersections, each intersections is black. I know the problem lies with the secondary ray bias, which I know how to fix in V-ray but I am new to Brazil and cant seem to find it in the render settings. Can anyone guide me to the settings that can make this problem go away.

Cheers!

Problem with IOR

garenc — Thu, 28 Jan 2010 10:11:05 GMT

Hello,

I would like to know how I can manage the IOR refraction control. When I change the indice IOR of glass for a flat piece, nothing moves.

Thanks.

Have i missed something (quite probable) but is there a patch to enable my brazil to operate with Rhino 5 wip on my 64 bit system?

Great archviz video

visose — Thu, 21 Jan 2010 12:10:16 GMT

In case anyone out there is working on archviz and thinks is doing a good job at it, think again:

http://www.vimeo.com/7809605

Everything is done by one guy (he lives in the same city as me).

Everything is rendered in Vray but i'm sure it can look as good in Brazil :P

You can't do this inside Rhino though, if you want those animations (shake cam, wind on plants, particles, etc.)

Problems Applying Materials (to a model from Solidworks)

Visario — Fri, 15 Jan 2010 14:53:16 GMT

Hi everyone,

I recently downloaded the Brazil trial for Rhino and it seems like a great tool. When applying materials and things to models I've made in Rhino everything works fine, but when I import a SolidWorks model into Rhino the Brazil materials don't seem to apply to the bodies. It'll all just stay as the defaut grey.

Is there a known issue with SolidWorks models being rendered in Brazil through Rhino, or should this be working properly?

Some extra things to note:

I'm using Windows XP-64bit, Rhino 4.0 (SR6) and SolidWorks 2008.
I've tried importing the model from SolidWorks as: .sldasm, .sldprt and IGES.
I've tried having materials applied to the parts in SolidWorks before importing them into Rhino.

Any help on this would be great. Thank you.

Setting the Viewangle and the resolution

trojax — Wed, 18 Nov 2009 15:35:08 GMT

Hi,

I need to set my camera viewangle to 7.3° horizontal and 5.5° vertical. Furthermore, I need to set the output Resolution to 1200 Pixels horizontal and a vertical value corresponding to my view angles.

Can you please help me by telling me how I can do this because I'm not to familiar with camera techniques.

Is there any possibility to do this also with RhinoScript?

Thank you very much!

More gamma issues

visose — Tue, 12 Jan 2010 20:56:51 GMT

I think something has changed since the last time i tried to use textures with rhino and brazil.

This image is rendered using the default rhino render with the gamma output set to 1 and the gamma of the texture in the adjustment panel set to 1:

This image has the gamma output set to 2.2 and the gamma texture set to 0.45 (1/2.2). Everything seems fine:

Now in Brazil:

This image has the gamma output set to 1 and texture gamma set to 1:

This image has the gamma output set to 2.2 and texture gamma set to 0.45:

Pick the odd one out. I don't think that's the way it should behave. If i inverse the gamma of the image manually in photoshop first it renders correctly.

More about tone mapping

visose — Tue, 12 Jan 2010 21:12:50 GMT

Maybe i don't understand this correctly, but why is there tone mapping set as default for HDR images? I would think that the correct way to render would be to have linear tone mapping in the HDRI environment and then use tone mapping in the final image after everything has been calculated. Since i only see logarithmic and Reinhard, how could those settings be altered to get linear tone mapping? As i mentioned in another post, it would be nice if the HDRI tone mapping was available for the final rendering. I think it would be relatively easy to add since the code is already there (or not, i really have no idea).

wish : post effect vignetting and camera simulation

jbshorty — Tue, 12 Jan 2010 18:13:55 GMT

Hi Andy. a wish to have a post-process effect for vignetting (radial darkening around the image)... thanks..

Also - would be nice to have simulated camera model and film stock for tone mapping. I've been doing this in post and there is of course a bit of quality loss. But direct from Brazil should be much better if we could do it...

RPC support (beta)

andylebihan — Mon, 04 Jan 2010 12:31:09 GMT

Hi all

Attached is a plug-in to allow V5 (32-bit only at the moment) to use RPC
objects. Drop all of the files into the plug-ins folder : c:\program
files\Rhinoceros 5.0\plug-ins\ and then load the RPC.rhp file.

The command "rpc" allows you to create an RPC object from an existing RPC
file or by using the Archvision ACM.

Renderers supporting the technology at the moment:

Brazil
RhinoRender

This plug-in will eventually be included in the V5 WIP - but for now, use
this one.

Polygons in stead of surface

trojax — Tue, 12 Jan 2010 08:09:25 GMT

Hi there,

I've some problems with rendering. Or more exactly: I got a parabolic mirror through which I'm looking at a picture in Rhino. The mirror is a steady plane, no polygon-thing. But as soon as I click on render view in Brazil, the parabolic steady surface is replaced by polygons what is verx critical for me.

Can anyone tell me how I can avoid Brazil from simplifying the surface or at least setting down the size of polygons to get lower influences on my rendering?

Thank you very much for helping me!

Daniel

Wish : disable switch for dispersion and DOF

jbshorty — Tue, 12 Jan 2010 07:10:00 GMT

Hi Andy. Just a request to add 2 more global switches to the settings dialog, one for chromatic dispersion and the other for DOF... Both can be ON by default of course... I just find these are both time-hogs and would be nice to disable while test rendering.... thanks... Jonah

Tutorial: Rendering Caustics in Brazil r/s

b_online — Mon, 04 Jan 2010 14:33:06 GMT

Could someone translate this tutorial for Brazil for Rhino ? (and attach example files with hdr and mat files?)

I am trying to render caustics for an ongoing project and can not find the way to do so correctly - I am about to give up...

I would trully appreciate it if someone would be kind enough to do a parallel tutorial for Brazil for Rhino:

http://brazil-rs.blogspot.com/2007/10/tutroial-rendering-caustics-in-brazil.html

My aim is to be able to produce similar results to the image on the right:
