Join our free webinar session to learn and create CAD model using Rhinoceros 3D, generate parametric texture with Grasshopper and create photorealistic renders using Keyshot.
In this Workflow Webinar we will explore CAD modeling, parametric design and 3D rendering of a DVD player.
You can watch the entire Webinar with this Link at the end of this post.
Let’s start by 3D modeling the base geometry in Rhinoceros 3D. With the given technical dimension, we will create rectangular extrusions, apply shell and Boolean operations to add details. To create the cable we will use Pipe command with a Degree 3 or higher NURBS curve.
Once we have the overall shape, we will apply a parametric texture on the top shell using Grasshopper 3D. Grasshopper is a Plugin that works as a visual programming language within Rhinoceros 3D. Unlike RhinoScript, Grasshopper requires no knowledge of programming or scripting, but still allows designers to create parametric and algorithmic designs.
So, to create the pattern, create a grid of points/planes with the rectangular dimension. Offset the border to cull the points near the edge of rectangle. After that use a point as an attractor geometry to control the radius of all the circles. We will need to remap the values to the min-max radius. We can also use a Graph Mapper to get a non linear mapping of the radius values.
With the curves, we will perform Boolean Difference with the top shell to transfer the texture. Be careful as this operation will take a lot of time to calculate. You might wanna do this in small batches. You can play around with the Graph Mapper and other parameters to get design variations.
Once we have the final geometry with the textures. Let’s open the .3dm (Rhinoceros native file format) into Keyshot. Keyshot is a rendering software used to create photorealistic product renders. We will use the pre-configured materials from Keyshot’s material library. After configuring the materials let’s create a 3 point light environment using the HDRI Editor. Hit Render and create the final image of your design concept!
