Detailed Description

Triangle primitive. Stores data needed for its rasterization

Member Data Documentation

dldx

float SRPTriangle::dldx[3]

Barycentric coordinates' delta values for +X movement

dldy

float SRPTriangle::dldy[3]

Barycentric coordinates' delta values for +Y movement

edge

vec3 SRPTriangle::edge[3]

Screen space edge vectors

edgeTL

bool SRPTriangle::edgeTL[3]

Whether or not the edge is flat top or left (0th edge: 0th vertex -> 1st vertex, etc.)

id

size_t SRPTriangle::id

ID of the primitive, starting from 0

invW

float SRPTriangle::invW[3]

1 / clip-space W. Needed for perspective-correct interpolation

isFrontFacing

bool SRPTriangle::isFrontFacing

Whether or not the triangle is front-facing

lambda

float SRPTriangle::lambda[3]

Barycentric coordinates at the current pixel

lambda_row

float SRPTriangle::lambda_row[3]

Barycentric coordinates at the beginning of the row

maxBP

vec2 SRPTriangle::maxBP

Maximum bounding point (screen-space)

minBP

vec2 SRPTriangle::minBP

Minimum bounding point (screen-space)

p_ndc

vec3* SRPTriangle::p_ndc[3]

Pointers to vertices' positions in NDC

ss

vec3 SRPTriangle::ss[3]

Vertices' positions in screen-space

v

SRPVertexShaderOut SRPTriangle::v[3]

Outputs of the vertex shader
