Development log

12 November 2019:

• Defined worst and best case

14 November 2019:

• Set up Unity project
• Steam VR Plug-in installed

20 November 2019:

• Created shader for Laser in using Unity Shader graph

Problem

• Shaders were shown pink

Solution

• Shader Graph only works with either LWRP (Lightweight Render Pipeline) or HDRP (High Definition Render Pipeline) of Unity
• For VR LWRP is better!

Laser Shader

Date: 20.11.2019

Laser Shader Shader Graph Nodes

26 November 2019:

• Created Grid shader for the Room in Shader Graph
• The UV translate in X and Y Axis by using time node

Problem

• The animations/ translation of UV is an infinite loop

Solution

• Possible solution would be to change the speed by setting the time to 0 instead of 1

Grid Shader

Date: 26.11.2019

Grid Shader Shader Graph Nodes

4 December 2019:

• Fixed the speed of the time for the grid shader by using multiplier node since boolean only has an input in Shader Graph

10 December 2019:

• Tried making another laser material that glows and is static

Problem

• There was no hollow around the light and neither shadows casted by the light

Solution

• One possible solution would be to use volumetric light

12 December 2019

• Auro Volumetric Light asset installed

Problem

• All Shaders were shown pink

Solution

• changed all shaders to LWRP
• Volumetric Lights still didn't show

13 December 2019

• Tried uploading the project to git hub

Problem

• Files too large hence the project couldn’t be uploaded

Solution

• Tried using Git LFS (Large File Storage) which also didn’t work

14 December 2019

• Tried using different Volumetric light asset which also didn't work

Problem

• Volumetric lights don't work in LWRP
• Some Volumetric lights still weren't shown right

Solution

• Load Volumetric Light scripts in the camera

to do:

• Aura volumetric lights not shown right
• Possible solution: Steam player prefab Camera setup wrong?

17 December 2019

• Aura Volumetric light was deleted because it didn't work with Steam VR player
• Created 2 types of laser one with Volumetric light asset and the other one with Steam plugin example prefab
• Updated room 3D asset

Problem

• Project still couldn't be uploaded on Github

Volumetric Light

Date: 17.12.2019

19 December 2019

• Test the project in Vive Headset
• adapt the size according to scale in VR
• Set Github Desktop

Problem

• Volumetric light can only be seen through one lens of the headset

20 - 21 December 2019

• used line renderer to create laser
• used asset laser machine
• set up the scene with the glowing light spheres
• animation of the spheres

22 December 2019

• applied textures to the room

3 January 2020

• completed one animation of the spheres

Problem still to solve

• volumetric light in VR
