Some freebies for video from Zach Poff

If you work with video, from webcams, video cameras or rendered, there are several complex manipulations that can be made a bit easier with some of the free utilities for realtime video editing. The website of artist and developer Zach Poff has some free applications for download. They are Open Source, but are made in MAX/MSP, which is the commercial counterpart of Puredata. And the applications are only compiled for Mac OSX.

Some of the things he presents:

Live Video Delay: view your video frames with a delay
Chroma Key Live: see a rough estimate of the effect of filming against green (or blue or purple) screen, live
Multiscreener: synchronize the playback of movies on different computers
Video Trigger: trigger sounds when something happens on certain parts of a video capture
...

Some of these functionality could be done in other systems, obviously, but having it in a precompiled utility will make it easier if one of his programs already does what you need. E.g. video installation reacting in realtime to visitors.

Improve usage of BIM during early design phases

When I was collecting ideas for a book chapter on BIM (that seemed to never have emerged after that), I collected 10 ideas, which I believe still reflect good recommendations to improve the usage of BIM during the early design phases. These ideas are related to BIM software, but you can apply them in any flavor, as long as you can model with Building Elements, Spaces and have control over representation. Introduction This article gives an overview of several recommendations and tips, to better apply BIM applications and BIM methodologies, in the context of the early design phases. Many of these tips are applicable in any BIM application and they are based on experience gathered from teaching, researching and using BIM software. Sometimes they could help software developers to improve the workflow of their particular BIM implementation. Tip 1 : Gradually increase the amount of information In the early design phases, the architect makes assumptions and lays out the main design in

Getting BIM data into Unity (Part 9 - using IfcConvert)

This is part 9 of a series of posts about getting BIM data into Unity. In this post, we’ll discuss the IfcConvert utility from the IfcOpenShell Open Source IFC Library to preprocess an IFC model for integration with Unity. This is (finally?) again a coding post, with some scripts which are shared to build upon. Conversion of IFC into Unity-friendly formats The strategy with this approach is that you preprocess the IFC-file into more manageable formats for Unity integration. Most Web-platforms do some sort of pre-processing anyway, so what you see in your browsers is almost never an IFC-file, but an optimised Mesh-based geometric representation. However, it wouldn’t be BIM-related if we’d limit ourselves to the geometry, so we will parse the model information as well, albeit using another, pre-processed file. IFC to Wavefront OBJ I used a test IFC-model and used the IfcConvert-utility converted it into OBJ en XML formats. The default way to use it is very simple:

Getting BIM data into Unity (Part 8 - Strategies to tackle IFC)

This is part 8 of a series of posts about getting BIM data into Unity. In this post, we’ll discuss IFC as a transfer format towards Unity. As with the previous post, this is not a coding post, although hints and examples are provided. Open BIM and IFC Everybody who ever met me or heard me present on a conference or BIM-lecture will not be surprised to hear that I’m a strong believer in the Industry Foundation Classes (IFC), an open standard, with already two versions published as an ISO standard, being IFC2x2 and IFC4 (but surprisingly not IFC2x3 which is widely used). In the ideal world, this would be the format to use to transfer BIM data into another environment, such as Unity. So what are our options? Looking in the Unity Asset Store Assimp is a library which supports multiple formats, including IFC. https://assetstore.unity.com/packages/tools/modeling/trilib-unity-model-loader-package-91777 I did a few attempts, but alas without any success. It is possib
