-## Project planning: Design Doc (due 11/8)
-Before submitting your first milestone, _you must get your project idea and scope approved by Rachel, Adam or a TA._
+Above image is a link to video :)
-### Design Doc
-Start off by forking this repository. In your README, write a design doc to outline your project goals and implementation plan. It must include the following sections:
+Train view is cool for anyone who wants to relax and enjoy the natural terrain winding out of the train window. We would like to provide a train view generator in Unity to simulate the passenger’s view point inside a large-window landscape express. We will provide a terrain generator to procedurally generate an infinitely-extending terrain landscape and a stylized shader to mimic the style of several pieces of 2D concept art. The project will finally be able to deliver an infinite tour aside by procedural stylized terrain view, with biomes and sky that can be fully customized by users in Unity.
-#### Introduction
-- What motivates your project?
-#### Goal
-- What do you intend to achieve with this project?
-#### Inspiration/reference:
-- You must have some form of reference material for your final project. Your reference may be a research paper, a blog post, some artwork, a video, another class at Penn, etc.
-- Include in your design doc links to and images of your reference material.
+#### Inspiration
+
-#### Design:
-- How will your program fit together? Make a simple free-body diagram illustrating the pieces.
+Project planning: Design Doc
-#### Timeline: -- Create a week-by-week set of milestones for each person in your group. Make sure you explicitly outline what each group member's duties will be. +#### Introduction +
+Train view is cool for anyone who wants to relax and enjoy the natural terrain winding out of the train window. In the game, we may generate a series of landscapes procedurally in an aesthetic pleasant style. Even better, the game will generate a mix of terrain which may be impossible in reality to create a fantastic viewpoint of the virtual world! -Submit your Design doc as usual via pull request against this repository. -## Milestone 1: Implementation part 1 (due 11/15) -Begin implementing your engine! Don't worry too much about polish or parameter tuning -- this week is about getting together the bulk of your generator implemented. By the end of the week, even if your visuals are crude, the majority of your generator's functionality should be done. +#### Goal +We would like to provide a train view generator in Unity to simulate the passenger’s view point inside a large-window landscape express.

-Put all your code in your forked repository.

+- Endless Terrain generator: We’re going to refer to some endless terrain generator blog and tutorial to generate the most diverse types of terrain.

-Submission: Add a new section to your README titled: Milestone #1, which should include
-- written description of progress on your project goals. If you haven't hit all your goals, what's giving you trouble?
-- Examples of your generators output so far
-We'll check your repository for updates. No need to create a new pull request.
-## Milestone 3: Implementation part 2 (due 11/27)
-We're over halfway there! This week should be about fixing bugs and extending the core of your generator. Make sure by the end of this week _your generator works and is feature complete._ Any core engine features that don't make it in this week should be cut! Don't worry if you haven't managed to exactly hit your goals. We're more interested in seeing proof of your development effort than knowing your planned everything perfectly.
+- Stylized shader
+ - [Reference images](https://www.instagram.com/oseo____o/?igshid=OGQ5ZDc2ODk2ZA%3D%3D)
+
-Put all your code in your forked repository.
+#### Specification:
+- Infinite procedural terrain generator along train track.
+ - Different terrain biome.
+ - Object scattering for biomes.
+- Procedurally generate some of the objects (trees, grass, etc)
+- Procedural skybox
+ - Changes color theme with respect to current biome
+ - Mountains in the distance
+ - Sun, moon, stars with animation
+- Cloud (To be decided: being a part of skybox or using other method)
+- Stylized shader of 2D concept arts.
-Submission: Add a new section to your README titled: Milestone #3, which should include
-- written description of progress on your project goals. If you haven't hit all your goals, what did you have to cut and why?
-- Detailed output from your generator, images, video, etc.
-We'll check your repository for updates. No need to create a new pull request.
+#### Techniques:
+- Terrain generation
+ - Unity Terrain / Hexagon grid / Coded mesh
+ - Noise sampling
+ - Dynamically generate & delete
+- Object generation
+ - Tree: L-system
+ - Grass: compute shader
+ - Stones: vertex shader
+- Object scattering
+ - Noise sampling
+ - Object pooling
+- Further research
+ - Smooth interpolation between biomes
+ - Cloud
+
-Come to class on the due date with a WORKING COPY of your project. We'll be spending time in class critiquing and reviewing your work so far.

+- Stylized shader
+ - In this week, we've played around the stylized shader. We used toon shader as a starting point and added paper post processing to produce a style mimicing the reference image.
+- Terrain
+ - We decided to use hex map for a relatively easy control of different biomes. Now we implemented a endless hex terrain generator that dynamically changes biome as the camera moves.
+- Biome
+ - We implemented a basic biome config system. Each biome is composed by 3 layers: near, mid, and far (from the train's view). The hex tile mesh and material can be defined for each layer. For instance, in the current video, there is a snow land biome where the snow is the near layer, the lake is the middle layer, and the black stone is the far layer.

+- Skybox
+ - In this week, we've added a stylized skybox. In next step, we will make the sky color be defined in biome config, so that the sky color changes gradually according to current biome.
+- Trees and Stones
+ - We added L-system trees and stones that user can choose to add for certain layers in a biome, and set the number to spawn. To be improved: add an object pool to control them to improve performance.
+- Sand ground shader
+ - We added a white sand ground shader to mimic the beach scene in one of the reference images.
+- In next days, we are gonna add more biomes, and do some performance optimization
