…structions-2021

Update instructions for Fall 2021

- Ideal diffuse surface model for shading
- Ray continuation with stream compaction
- Thrust sort for memory coalescence

- perfect specular reflection
- ideal diffuse shading
- transition between half-reflection & half-diffuse

- avoid new ray colliding with the surface by increasing the floating point offset

* remove or move "using namespace std" into source

* finished part of core features

- Ideal diffuse surface model for shading
- Ray continuation with stream compaction
- Thrust sort for memory coalescence

* add `static` qualifier to device arrays

* increase hidpi scene resolution

* add `depth` to RNG generator in `shadeMaterial`

* add `const` qualifiers

* move extract material IDs to `computeIntersections`

* remove redundant `iterationComplete` variable

* finish core shading features

- perfect specular reflection
- ideal diffuse shading
- transition between half-reflection & half-diffuse

* increase lighting effects

* add Cornell variant -- multiple balls

* fix floating point issue in `getPointOnRay`

- avoid new ray colliding with the surface by increasing the floating point offset

* decrease light intensity

* move constants to static_config.h

* fix incorrect light rendering & reflections

* fix specular material color value in multiball scene

- always normalize ray direction before calculation
- always use true_normal for reflection & diffusion

- bug due to some magic floating point number
