XG Rendering - Which do you prefer?

[Cary OConnor]

 

IRONCAD "XG" offers a wide variety of realistic rendering capabilities as well as common material catalogs. Enable the material catalogs by turning on the "Rendering" catalog set which includes glass, wood, plastic, paints, and other materials. Keep in mind when rendering, the use of 3D Environments enhances the rendering with more realism that is less taxing on the system compared to many light sources and effects.

 

Which of these renderings do you think is the better rendering?

[dcanelhas]

I think the rendering with the lighter background is better because the reflected light from the background helps define the shape of the spring, and color-wise ties the reflected color from the top of the metal together with some visible element from the scene, making it less artificial. Also, the lighter background produces a clearer silhouette for the whole part, making it more recognizeable. This would be good if it were a catalog item that had to be shown ias small thumbnails too.

//well, on second inspection it seems about the same, the top blends in to the background in the right image, and the bottom blends in on tha left image. Ideally, perhaps the background would have a slight gradient that could yield a good contrast on both top and bottom of the part.

 

The faint reflections and shadows in the ground plane also help to define it as a physical object on a surface rather than a physical object floating around in outer space.

The right one with the lighter background is the best, it look more realistic.

[cborer]

To me it looks as if they are the same!

...just background is different.

Was this a test?

Hi Carlo,

 

The floor is really the only difference in the scene. However, the Global Illumination and Radiosity will have a different result. The color can carry into other reflections and light to highlight the scene a bit different.

I prefer the rendering on the right - the interaction between the part & the floor (shadow & slight reflection) definitely gives it an added sense of realism.

[rfisk]

The one on the right is better because of the reflected light helping ro define the parts.

Realistic rendering is the most time consuming aspect of completing a design project. Just selecting and setting the basic lights to get decent surface definition and shadows consumes a lot of wait time, even with mid range graphic cards and multiple gigs of ram.

When the products are diverse composed of different sizes, shapes and proposed materials, there is little chance of using and saving the same global settings.

For everyone's edification, how long did someone spend to render that part after the modeling was complete? What was the computer setup? Would it be possible to see what all the rendering settings are? Is there a preferred sequence of rendering settings that makes the process faster to the end result?

[Guest EricFoy]

The spring needs some custom ends on it. Then it would look realistic.

 

 

 

 

 

 

(I like the one on the right.)

[tlehnhaeuser]

obvious choice, right side

[cborer]

Personally I also liked more the one on the right.

 

Hi can you post the settings for that sample?

Maybe even with the sample.

I would like to play that through

Thanks

Well the file is big due to the 3D Enviornment used. Basically here are the steps used to render:

 

1. Open the Rendering Catalog from the Catalog Sets.

2. Drop the Red Car Paint on the spring.

3. Drop the Rough metal for the bolts, Brushed for the two connectors ends, chrome for the cylinder, and brass for the fittings.

4. Added Dosch (Car Environment) 3D Environment and increased the exposure to 1.5.

5. Turn on GI (Full) and turn up Radiosity a few notches.

6. Then it is just a matter of camera angle and time.

 

Render at lower settings at first to get the look. Then turn it up to meet the goal. It took about 14 min for the high res version to complete.

Where can i get the 3D environment? Maybe we can run a test on the crazy file I sent you with environmental lighting and see how it renders.

 

The shocks both look great, but I prefer the higher contrast of the one on the left.

[Cary OConnor]

On the partner CD (or partner section of the DVD), there are links to the Dosch Environments. You can use those. Also, there are basic lighting 3D environments in the images folder.
