YOUR PROJECTS/
Estimate Time & Cost
|
This page will help you to estimate the cost of a Cooperative Project. First, let's calculate the Samples Per Pixel (SPP) gain you can expect from the RANCH, compared to your system.
|
| |
Download the caterpillar_5 scene and run it on your system with a Halt time of 3 minutes,with the default 1000 x 700 definition. When this is done, enter the SPP reached in the 'Your SPP' field, then click on 'Compute'. The SPP difference factor between your system and the RANCH - let's call it DELTA - will be displayed.
You can apply this DELTA factor to all your projects. For instance, if your system takes one hour to reach a given SPP, you know that in the same amount of time, the RANCH will reach this SPP * DELTA. The RANCH reaches SPP = 1270 in 3 minutes on the caterpillar_5 scene (with Indigo 3.2.5, x64).
A concrete example:
Your SPP on the caterpillar_5 test is 5, and you want to reach a final SPP of 500 on your project: how much RANCH time do you need? Simple: in your case, DELTA=254. You just have to render your project on your system with a Samples Per Pixel limit of ~2 (500/254), and note the time needed to reach it. That's all you need to know, as the RANCH will need the same amount of time to reach an SPP of 500. If it sounds good to you, you can then enter this time in the cost estimator at the bottom of this page.

How to use the cost estimator below:
|
| |
|
In the first field, enter an estimation of the preparation time of your project (loading textures, building meshes, etc.). This is the time needed for various calculations before the rendering itself begins. Two minutes are automatically added to account for the distribution time of the scene across the whole network.
|
|
|
|
|
In the second field, enter the render time limit you will specify when you submit your project on the RANCH.
|
|
|
|
|
In the third field, enter the size of the IGI file generated by your project, in megabytes (MB). To do this, simply launch a render at full resolution on your computer for a few minutes, until Indigo has written on disk the first IGI. Then enter its size in the 'IGI size' field.
Gathering and merging IGIs on all the RANCH Runner nodes takes 4 to 5 minutes with 1 GB IGI files (around 200 MB per minute). The individual IGI size limit that can be processed with our parallel multi-merging technique is around 5 GB.
If the render time of your cooperative project is >= 60 mn, the IGI gathering+merging phase is FREE!
