Export Grasshopper LadyBug Simulations to Realtime platforms

02/23/2023 Laurent Lescop Laisser un commentaire

Exporting color scale renderings from Ladybug simulations outside of Rhino after baking can be challenging as most formats tend to lose the colored information. What steps can we take to address this issue?

Grasshopper result

Bake the results from Ladybug.

Export the 3D file to WRML

Check Vertex Colors

Open Blender

Import the WRML file

The file arrives black

Change Material to Attribute to see the color gradient

Transferring Attribute to Texture

First unwrap the geometry

Select shape -> UV Editing

Object Mode -> Edit Mode

Be sure that all faces are selected (it should be orange)

UV -> Smart UV Project

In Shader Editor

Add a Color Attribute, Right Button click to reveal Col

Link Color to Base Color

Add an Image Texture

Click New and choose 2048×2048 resolution

Click OK

Switch Evee to Cycles

Down to Bake

Bake Type Diffuse

Contribution : Color

Select Texture image panel AND Geometry and then click Bake.

It takes time…

Connect Texture Node to Base Color and activate Color Texture

Secure save the image

Reload if necessary

Export file

Light Simulation RGB additive with IES

11/28/2022 Laurent Lescop Laisser un commentaire

Foreword

In this tutorial, the idea is to verify if render software properly simulate colour mixing. For that, we will use, when possible, IES files in order to mimic as much as possible real phenomena. It extends and refreshes the previous tutorial on the same topic: http://www.keris-studio.fr/blog/?p=5475

Colour mixing refers to Grassmann’s laws (https://en.wikipedia.org/wiki/Grassmann%27s_laws_(color_science)). In colorimetry, Grassmann’s laws govern the superposition of colours. They serve as the foundation for all colorimetric calculations. Hermann Grassmann’s 19th-century studies of human colour perception led him to formulate three laws in his 1853 article « On the Theory of Colour Mixing. » (Grassmann, H. (1853). « Zur Theorie der Farbenmischung »). Continuer la lecture de Light Simulation RGB additive with IES →

Coraulis GeoFun

This is workflow to create a scene in Coraulis. It is done in Blender, but can be realised any similar 3D software. The first step consists in creating a “landscape”. We used the Geometry Nodes to create it, but can be done the usual way or with another software equivalently. It is then lit which can also be done anywhere else. Then the camera is animated along a path. The rendering process uses the Equirectangular 360 Camera which is built in Blender. But we can find the same camera in Cinema 4D, 3DsMax or Twinmotion. The 360 film is then recut to fit Coraulis requirements. Step by step with Blender, C4D or Max, we can create an amazing experience with plying with the context, the movements or the light.
