How to – Add a background image in a stereo panorama rendering

How to – Add a background image in a stereo panorama rendering

A stereo panorama rendering created using A360 rendering can be downloaded as a zip file.

Once you download the zip files and unzip it, you will see the following contents in it:

image.png – The main high resolution image

image.jpg – A lower resolution image for preview

imageL.jpg and imageR.jpg – The left eye and right eye

imagespano.html – The html file

twgl-dist.js – Javscript file

readme.txt  –

Here are the steps to adding your own custom background
  • Open image.png in an image editing software such as Photoshop
  • Since this is a png file, it has an alpha mask and you can composite your custom background.
  • Once editing is done, save this as a separate file or you could overwrite the original. But the final file has to be named image.png 
  • Now you have to generate the left and right eye images and the preview image
    • Crop the top-half of the image and Save As imageL.jpg
    • Crop the bottom-half and Save As imageR.jpg
    • For the preview image, Save imageL.jpg as image.jpg. Reduce the size of this image to 1/8 of the original size. For eg: 9216×1536 will become 768×128 pixels.
  • All your images are now ready. If you want to preview how it looks on your computer, open Firefox browser (Chrome does not let you open local files) and drag pano.html to it. You should see a pixelated preview for a brief moment. After it clears up, you will see the new panorama with your composited background image. Example of the link: file:///C:/Users/xyz/Desktop/stereo_pano/pano.html. You should do this to check if your composite looks fine and if there are any edits required.
  • In order to view it in the browser on your mobile device (this is what you really want), all the files in the zip file have to be hosted to your website. They cannot be uploaded back to Autodesk’s site, which happens when we generate a URL for your rendered stereo panoramas

A narrated take on Architectural Plan illustration for beginners. Nothing too outrageously crazy but a lot of fun and hopefully it helps out.
This time it’s been slowed down for all to understand and see

Create Seamless Textures for Rendering and Visualizations

Create Your Own Seamless Textures for Rendering and Visualizations.

If you are not sure what I mean by “seamless” here are two examples…

This is a textures that is NOT seamless… Notice how you can see where the image repeats itself…

 

This is a seamless texture… Notice how you cannot tell where the image repeats itself…

The hardest part about finding good textures is finding ones that are seamless.  There are two ways to approach such a problem.  One is to find a texture online that is not seamless and make it seamless.  The other is to take a photo of the texture you want and make it seamless…  With either approach the following tutorial will teach you how to make a seamless texture from any image file…

The tutorial “Creating-custom-texture” from “Rendering with Revit”  Paul Aubin are more detailed and explained in the revit project.

Revit 2016 – Rendering Engines

Revit 2016 – Rendering Engines

Some years ago we went through a changeover from Accurender to Mental Ray as Autodesk focused on Mental Ray as their preferred rendering engine for several of their products. If you didn’t know it already Mental Ray belongs to Nvidia. Autodesk has purchased companies, and their products, more recently that allows them to focus on using what is now their own rendering engine; which is being called Raytracer. Don’t confuse it with the Visual Style called Raytrace This means we find ourselves in another period of rendering engine transition from Mental Ray to Autodesk Raytracer instead. Revit 2016 has both Mental Ray and Autodesk Raytracer options available to us when we decide to render via our desktop (not using Cloud Rendering).

As I understand it they are motivated to go through this in order to provide what they believe will be simpler yet higher quality and faster rendering options because they will have more control over the engine being used; it’s theirs, not someone else’s. Unfortunately it takes quite some time to plug in and unplug something so intrinsic to how Revit works. I believe that, if things go according to plan, we’ll probably just find the one option (Raytracer) in the next full release of Revit.

Considering the visualization products available today like Revizto, Lumion, Fuzor and Enscape, which all offer a very impressive real time rendering environment as well as integrating well with Revit, I can’t help but wonder if the development team is really in tune with the market. Maybe they have something up their sleeves we just can’t see yet? I hope so. For a very basic comparison I took a model I made recently during a training session and used both rendering engines with just exterior lighting. I used the same location each time, southern CA (where I live).

This is using Mental Ray (3:27 seconds at Medium)

This is using Raytracer (2:53 at medium)

This time I switched to rending the same model and view using the Draft setting. This is using Mental Ray (51 seconds at Draft)

This time using Raytracer (39 seconds at draft)

For each rendering Raytracer was the faster engine. The quality difference between the draft renderings was much more noticeable with Raytracer’s result being cleaner and clearer. Raytracer’s Draft and Medium was much more consistent than for Mental Ray. If rendering is your passion then I encourage you to read Daniel Stine’s article about this new development in Revit. It was published at AECBytes.

A quirky outcome of this transition is how the two engines deal with the Adjust Exposure feature.

With Mental Ray we can render and then click Adjust Exposure and tweak the result, seeing the changes in the image immediately. With Raytracer we can’t do that. We CAN use Adjust Exposure first and then render, which makes no sense to me at all. This means we have to render first, make some adjustments to the exposure (which is adjusting blindly), render again to see if it provides a better result…repeat.

It’s my understanding that it is what it is…for now..
