Using Blender on a Laptop with a Trackpad

After futzing CentOS 7 on my old Samsung Q330 laptop, I thought it would be fun to see if the old hardware from 2010 would be capable of running Blender. After all, the team have recently added CentOS as a new pre-built package to the list of downloadable options, and for me that was the perfect opportunity to try it out.

Turns out my Q330 only runs OpenGL Version 2.1, which means it can’t run Blender 2.8+. However it’s still capable of running 2.79, and it made me smile to see it full screen.

Of course trying to move anything on the screen proved to be difficult, because I had never done that before with a standard trackpad. My Mac has one, and it behaves beautifully with gestures out of the box, but I guess Windows and Linux users don’t have that luxury, even if a trackpad is present.

How do we navigate 3D space in Blender then, if there’s no mouse nearby? Well I’ve just found out, and I’d love to share it with you. I’ve only been able to test this in Blender 2.79, but I’m assuming

Shattering my Logo in Blender – 3D Shenanigans #15

On this week’s live stream I’ll take my 3D Shenanigans Logo and shatter it into pieces, to build a creepy backwards animation using the Cell Fracture add-on in Blender 2.79. I’ll start by explaining how the tool works, then we’ll move on to building the logo from scratch, add materials, and then we’ll build something …

Animating Numbers with Blender and DAZ Studio – 3D Shenanigans #12

In this live event I’ll show you how to create 3D Text Objects in Blender 2.8, then bring them in to DAZ Studio to animate and render. We’ll animate a single number first, then apply the same animation to the other numbers and add small variations using aniMate. Other than that, I’m happy to answer …

Using a Density Map with the Blender Particle Emitter (Replicator)

In this final episode of our serves I’ll show you how to create and apply a Density Map for use in Blender’s Particle Emitter. This will allow us to specify where objects are replicated and how may we want at which point. I’ll also explain how to invert the map. I will touch on how …

Adding Materials to our Objects in Blender (Cycles)

In this episode I’m giving our objects some colour with simple shaders: I’m making the grass green, give the ground an earthy brown and add a shiny golden touch to our logo. I’m also covering the logo with another replicator, simulating an interesting effect. This is part 4 of a mini series about how to create …

Replicating an Object with Blender’s Particle Emitter

In this episode I’m building several simple grass stalks and replicate them along a plane using Blender’s Particle Emitter. I’ll talk you through the scary options we need and explain some of the concepts in using the Particle Emitter as an Object Replicator. This is part 3 of a mini series about how to create a …

Creating a Logo from a Raster PNG in Blender

In this episode I’ll show you how to use the SVG file with curve information and turn it into an extruded logo using Blender. I’ll setup the scene and ground plane, get the camera ready and turn the default light into a strong side light. This will serve as a starting point to creating our …

How to turn a Raster Image into a vectorised SVG in Photoshop

The other day I wanted to convert a logo into a path, so that I could use it as a shape in Blender. It was in fact the WordPress logo that was provided as a PNG or PDF from the WordPress Branding section.

The trouble was, both the PNG and the PDF are rasterised, and as such cannot easily be used for an extrusion in 3D as an SVG file would. The question then was, how do I convert an image into an SVG in Photoshop, so that I could import it into Blender?

It took a bit of fiddling, but here’s how I did it.

Quick introduction to SVG Files

SVG files can actually contain three types of data:

  • Vector Graphics, such as paths (which is what we want)
  • Raster Graphics, such as bitmap images (which we have, but don’t want)
  • and Fonts

What I needed in Blender was indeed a Vector Path. Although the other two data types can be contained in an SVG file, Blender can only read path information at the time of writing. It makes sense too, because really I’d like to the path information available as a curve in Blender, not the potential raster or font information.

I’m mentioning this here because

  • a.) I didn’t know this, and
  • b.) importing an SVG containing either fonts or raster graphics will import nothing into Blender – which had me stumped.

Thanks to cegaton on Blender Stackexchange for this explanation!

Hence, for Photoshop to export vector data instead of raster data in our SVG file, we need to jump through a few hoops – but it is possible. Let’s see how!
