Common PFX in Hexels include blur and color adjustment. PFX are similar to filters in Photoshop in that they modify an existing image according to a set of rules. Post-processing (PFX) shaders will be used for our two examples.
Hexels effects code#
For developers, this is useful because code changes can be seen immediately without having to recompile and re-run. Another important feature of shaders is that they can be loaded and reloaded while the application is running. Shaders run on the GPU far faster than compiled code runs on the CPU, which means that post effects can be re-calculated every time Hexels draws without causing a noticeable slowdown. What is a Shader?Ī fragment shader is a short program that runs on the graphics card (GPU) to determine the color of an individual pixel. Please note that as we improve Hexels, this information may change, and any shaders you make may need to be updated for future versions, but we’ll try to keep as much backwards compatibility as possible. If you need a refresher on GLSL, visit the following links: A basic knowledge of GLSL 1.2 (OpenGL Shading Language) is highly recommended, but anyone with some programming experience should be able to do something with this tutorial. This tutorial gives an overview of shaders and how they’re used in Hexels, and then shows a couple simple examples of adding custom shaders, allowing Hexels to perform new tricks. Shaders allow these effects to be calculated in real-time for Hexels’ vector graphics. One of the coolest new features in Hexels 2.5 is the use of fragment shaders for layer blending and post effects (PFX).

Hexels effects trial#
Explosions, boats and lettering were added to existing layers to fill out the scene.Ĭreate your own parallax animations using the 14 day trial of Hexels. The illusion of depth was enhanced by reducing the opacity for layers in the distance. This creates invisible frames in between every frame to smooth out and slow down the final animation. The Frame Tweening values were increased in the Animation Settings window. The Frame tool (F) was used to crop any unwanted layer edges from view. Remember, layers beyond the pivot point (Layer 0) move in opposite directions to layers ahead of the pivot point. To end the animation at the starting position, Frame 1’s Transform keyframe was copied and pasted to Frame 8.Īn isometric diagram of the final animation. The Transform Tool (T) was used to keyframe the Transform of Frame 1 for Layer 1 moving slightly to the right, then another at Frame 5 moving in the opposite direction. Layer 0 (shaded grey in the image) is our static pivot point that other elements orbit around. I’ve switched to Timeline mode and added 7 frames to the animation track. I added my characters and arranged all the layers in order of depth The top layer contained the nearest element and the bottom layer contained the farthest. In order to animate the parallax effect, the buildings and bridges needed to be cut and pasted into their own pixel layers.
I drew a cityscape on a Pixel layer using the Line tool (L) with my pencil size set to 5.
Hexels effects 1080p#
I started with the Pixels Trixels 1080p template and doubled the canvas size from 1920×1080 to 3840×2160. The closer an object is to the pivot point, the less it appears to move. It’s created by looping multiple tiling planes at varying speeds.Īn Orbital Parallax effect, on the other hand, simulates a camera orbiting a pivot point.Įlements beyond the pivot point move in the opposite direction to those ahead of the pivot point. This animation is an example of Asymmetrical Scrolling. Foreground layers move at a different speed to background layers depending on their perceived distance from the camera. What is a Parallax Effect?Ī parallax effect is an illusion of depth using layered 2D elements.
Hexels effects how to#
This guide will show you how to use Hexels to create a dynamic, comic book style sequence with an orbital parallax effect.
