gamasutra – The cost of games
www.gamasutra.com/blogs/RaphKoster/20180117/313211/The_cost_of_games.php
Think of the whole industry as a mature market. We’re running out of platforms shifts that reset costs.
Get good at systemic design, design for retention, design for community. Basically, think like an MMO developer. Yeah, that means designing everything as games as a service.
Embrace procedur-ality.
But also embrace brand-building and marketing, because you ain’t gonna survive without it. This market is going keep getting more crowded.

About green screens
hackaday.com/2015/02/07/how-green-screen-worked-before-computers/

Chroma Key Green, the color of green screens is also known as Chroma Green and is valued at approximately 354C in the Pantone color matching system (PMS).
Chroma Green can be broken down in many different ways. Here is green screen green as other values useful for both physical and digital production:
Green Screen as RGB Color Value: 0, 177, 64
Green Screen as CMYK Color Value: 81, 0, 92, 0
Green Screen as Hex Color Value: #00b140
Green Screen as Websafe Color Value: #009933Chroma Key Green is reasonably close to an 18% gray reflectance.
Illuminate your green screen with an uniform source with less than 2/3 EV variation.
The level of brightness at any given f-stop should be equivalent to a 90% white card under the same lighting. -
Equirectangular 360 videos/photos to Unity3D to VR
SUMMARY
- A lot of 360 technology is natively supported in Unity3D. Examples here: https://assetstore.unity.com/packages/essentials/tutorial-projects/vr-samples-51519
- Use the Google Cardboard VR API to export for Android or iOS. https://developers.google.com/vr/?hl=en https://developers.google.com/vr/develop/unity/get-started-ios
- Images and videos are for the most equirectangular 2:1 360 captures, mapped onto a skybox (stills) or an inverted sphere (videos). Panoramas are also supported.
- Stereo is achieved in different formats, but mostly with a 2:1 over-under layout.
- Videos can be streamed from a server.
- You can export 360 mono/stereo stills/videos from Unity3D with VR Panorama.
- 4K is probably the best average resolution size for mobiles.
- Interaction can be driven through the Google API gaze scripts/plugins or through Google Cloud Speech Recognition (paid service, https://assetstore.unity.com/packages/add-ons/machinelearning/google-cloud-speech-recognition-vr-ar-desktop-desktop-72625 )
DETAILS
- Google VR game to iOS in 15 minutes
- Step by Step Google VR and responding to events with Unity3D 2017.x

- Basics details about equirectangular 2:1 360 images and videos.
- Skybox cubemap texturing, shading and camera component for stills.
- Video player component on a sphere’s with a flipped normals shader.
- Note that you can also use a pre-modeled sphere with inverted normals.
- Note that for audio you will need an audio component on the sphere model.
- Setup a Full 360 stereoscopic video playback using an over-under layout split onto two cameras.
- Note you cannot generate a stereoscopic image from two 360 captures, it has to be done through a dedicated consumer rig.

Photogrammetry from 360 cameras
Agisoft PhotoScan is one of the most common tools used, but you will need the professional version to work with panos.
These do not support 360 cameras:
– Autodesk Recap
– Reality Capture

CloudCompare – point cloud editor for photogrammetry
CloudCompare is a 3D point cloud (and triangular mesh) processing software. It has been originally designed to perform comparison between two dense 3D points clouds (such as the ones acquired with a laser scanner) or between a point cloud and a triangular mesh. It relies on a specific octree structure dedicated to this task.
Afterwards, it has been extended to a more generic point cloud processing software, including many advanced algorithms (registration, resampling, color/normal/scalar fields handling, statistics computation, sensor management, interactive or automatic segmentation, display enhancement, etc.).
