Already a little over 2 months since the last release but finally I got this one out. This is quite a big release with a lot changing under the hood which meant a lot of refactoring and then a few headaches getting the mac version up to speed but I got there in the end. These are the main changes: API Re-factor which changes how you get sprites from TimelineFX to the GPU. This is a really positive change that I’m happy with. Before this change, in order to draw sprites that timeline fx produced you would basically have to Read more
Alpha 30 Released (finally!)
Another new alpha version has been uploaded with more new features and improvements. Here’s an overview of some of them: 2d Paths Paths are now available for 2d as well as 3d. They have pretty much exactly the same features as the 3d paths with the obvious exception that there’s no z axis for some of the settings. Otherwise the same generators are there plus I added a basic selection of preset paths under the Add Emitter menu. There’s still a lot I want to do to improve the interface for creating paths such as direct node manipulation and Read more
I’ve been very busy with the latest releases that I didn’t have the time to update these blog posts but thought I should have a quick catch up so here’s a round up of the latest additions. Paths A big new feature is an emission type called paths (currently 3d only). This is where you can create a path that particles can spawn and travel along allowing for a great range of new effects and emitters to be created. This is a feature that is still under development as it’s not easy to create the interface that makes them Read more
Just a quick update! I’ve mainly been working on adding spline paths in to the library the last month which I’m still working on but I wanted to just get a new alpha out which fixes a bunch of bugs and also introduces a simple but very effective feature where you can now spin particles on their pitch and yaw axis. Previously you could only spin particles on the axis that faces the camera but now you can set the Particle Rotation settings to free align and then adjust the spin attributes under particle behaviour. I also added the ability Read more
This is the final update for version 25 where I’ve been focusing on help and documentation. In this version I’ve added 2 new features to help new and existing users get a quick insight into how each effect and emitter works. Insights I’ve introduced a new tab labelled Insights. On this tab is auto generated documentation for each effect that gives a brief overview of the main properties that are used. Each property that is referenced has a link that you can click on that where that property is so you can easily get to grips with where things Read more
So I got an ARM based Mac this weekend and got it compiling to create a universal app for ARM and Intel base Macs. I still have my old Intel based Macbook to test with and it seems to work fine on that too. Doing the ARM version meant that I had to map all of the Intel intrinsics to the ARM equivalents which was reasonably straight forward. A few work arounds were needed here and there and in other situations it was actually easier to do with the ARM intrinsics. Having the library also build for ARM processors is Read more
I’ve just uploaded a new version for Intel based Apple Macs. Unfortunately I have a MacBook Pro from 2015 which is intel based, and whilst I can cross compile to ARM from there there’s no way for me to properly test without a newer ARM based Mac. I would need to test as the code uses a lot of Intel intrinsics for SIMD instructions that don’t all map 1 to 1 to the ARM equivalents. I have already made a start on this but will wait until I get my hands on an ARM based Mac before continuing. I’ll probably Read more
I just uploaded the latest alpha which builds on the last version with a brand new help section! This help is entirely in the editor and searchable by key word. It even works like a simple browser where you can go back and forward to previous sections you were looking at and it also has links that link either to other help files in the editor or externally too. I also added an About pop up that opens up on start up. It’s pretty basic for now but I can improve it at a later date. Both the about and Read more
This is the first update where I’m trying to improve the usability of the editor. In this update I’ve completely reworked effect and emitter properties and attributes. Before there were 2 separate lists with properties where you adjust things like the draw order, the emission type, spawn options etc. And attributes where you would change how the particles behave overtime. I’ve combined these all into the same tab and made them all searchable by keyword. I have also rearranged the attributes so that they’re grouped together more logically. As you can see in the screen shot, instead of all the Read more
Happy New Year! Alpha version 24 has now been released. It has been a very busy period for me over the holiday, and a real time of learning new things. Bounding Boxes for Sprite Data Something I wanted to accomplish was calculating the bounding boxes for each frame of a sprite data animation. This is where you can pre-record your effects and simply use a compute shader to interpolate the compressed data to playback the effects. It is a very fast way to use effects, as almost everything happens on the GPU. All the CPU has to do is Read more
