创建真实感效果一直是计算机图形学中的最难的工作之一。有一个非常精细的模拟和创造性的控制之间的平衡。在快节奏的后期制作的世界，这是特别真实。在这8周的课程大卫·亚历山大将带你通过整个镜头，最近完成了一个重大的电视连续剧。

Creating photoreal effects has always been one of the hardest jobs in computer graphics. There’s a very fine balance between simulation and creative control. This is especially true in a fast paced post production world. In this 8 week course David Alexander will take you through the entire shot recently completed for a major TV series.

您将学习如何程序产生裂缝，坠落的碎片和尘埃，复制沿物体表面，工作与粒子的情况下，表情和动态模拟生产验证的技术。每一步的过程包括：建模，脚本和表达式，仿真，灯光，阴影，渲染和合成。当然也包括大卫的自定义实例的烘烤和对象复制脚本已广泛应用于生产。

You will learn production proven techniques on how to procedurally generate cracks, falling debris and dust, replicate objects along a surface, work with particle instances, expressions and dynamic simulations. Every step of the process is covered: modeling, scripts and expressions, simulation, lighting,shading, rendering and compositing. The course also includes David’s custom instance baking and object replication scripts that have been extensively used in production.

Week 1:

production timeline

particle sims vs rigid body sims

naming conventions

image based geometry generation techniques

large pieces modeling

homework: Generate large chunks of dirt based on a fracture image.

Week 2:

root modeling

v_scales script overview

root replication

homework: Model the dirt wall with the roots. Replicate the roots randomly

along the wall using the provided v_scales script.

Week 3:

dirt wall modeling

simulation prep

large pieces simulation

part_pivot script overview

particle scripting techniques

homework: Prep the models for simulation. Using the provided part_pivot

script convert the models to particle instances. Control the dynamic simulation

of the pieces by adding and modifying the per particle attributes.

Week 4:

bake simulation

instance_bake script overview

convert instanced geometry to polygons

animation tweaking

generate emission maps

homework: Bake out the simulation using the provided instance_bake script.

Tweak the resulting animation. Generate emission maps for secondary

particle emission.

Week 5:

small chunks modeling

particle instancing techniques

small chunks particle instancing

small chunks simulation

falling dust / debris simulation

debris rendering

homework: Model and simulate smaller chunks. Simulate and render falling

dust / debris.

Week 6:

dust simulation

dust rendering

shading / texturing

homework: Generate a dust cloud. Work on shading and texturing all of the

elements.

Week 7:

setting up the render passes

lighting

rendering

homework: Set up the render passes and light all of the elements. Render out

all of the passes and prep for compositing.

Week 8:

compositing

layer modes

camera shake expressions

color correction / grain

final render
