Architectural Visualisation in Rhino V5
This is Phil Cook from Simply Rhino, in this video we are going to look at some of the improvements in Rhino v5.0 that are particularly useful for visualisation and presentation in architecture and its related industries.
When we are working in perspective mode and particularly if we have a lens length that is quite wide then fairly obviously I am going to have some distortion of the verticals. I can overcome this with the new 2 point perspective mode in Rhino3d v5.0 and just like an ordinary perspective viewport I can change the lens length so that I can minimise the distortion in perspective mode whilst maintaining my verticals.
We have looked previously at the rendered shadows mode in another short video but there are a couple of interesting options in this mode that may appeal to Architects. First of all, if we go to the rendered shadows options, rather than using the rendering material we can override the rendering material with just a single object colour. This allows me to create a visual, which is much less about the materials used in the building and more about its formal qualities.
I have now brought in some more geometry and switched back to showing the rendered materials, next I am going to go to my Rhino Options and you will see we now have a new rendering section here and I now have the control to turn on the sun and I can set the sun for a particular location, in this case, Madrid and I can set it for a particular time of day and calendar date and I can apply that. We will now see that our shadows match our sun location.
To add more illumination to this scene we can add in another feature, which is the skylight. This looks over bright in the rendered shadows preview but if we actually render out the image you will see that the exposure looks correct and here is the final image with the nice sharp shadows from the sunlight.
Once I have moved the camera inside the building again the skylight option can be useful. In rendered view my view is ok but when I switch to rendered shadows option view because there is no light entering the building I need some additional illumination, I can do this easily by going to options and turning the skylight on and I have now got my illuminated view.
Another new option inside Rhino3d is in the Rhino3d Render options, this is using Rhino3d’s own built in renderer and now I’ve got the option to add an environment to this scene, so I will create a new environment here and I am going to add an HDR image in the background of a sky. I can set the projection here of this image and perform some other editing to it, i just select that for the moment, you will see now that my HDRI is influencing the colourisation of the scene as well as giving me a background. If I pan around here you will see this background is projected correctly.
Now of course at the moment the sun location here does not match the shadow direction but I can go back into my options here edit the environment, go into the image and I can change the azimuth direction here, which moves the sun to the centre of the image here. Now my sun seems to be little more correct.
Let’s take a look at a render of this again inside rhino3d render, and here is the completed image.
Again, something else that’s new in Rhino3d version 5 is the frame buffer window that we have here and this now gives us the opportunity of for example editing the exposure, by changing the gamma here, i can also add some post processing affects here for example depth of field, which I can get to the properties of, pick where I want my sharp area to be and you will see sharp around here, blurred beyond it. So some nice quick effects here that we can use inside the basic rhino3d render.
