Member Data Documentation

latitude_attribute_name

std::string_view latitude_attribute_name = "@latitude"

The name of the output vertex attribute storing the latitude values.

If empty, no latitude attribute will be created.

longitude_attribute_name

std::string_view longitude_attribute_name = "@longitude"

The name of the output vertex attribute storing the longitude values.

If empty, no longitude attribute will be created.

use_u_as_profile_length

bool use_u_as_profile_length = true

Whether to parameterize the profile length as the U coordinate in the UV mapping.

If false, the V coordinate will be used for the profile length.

profile_angle_threshold

float profile_angle_threshold = static_cast<float>(lagrange::internal::pi / 4)

The maximum allowed angle (in radians) between consecutive profile segments for it to be considered as smooth.

UV and normal will be discontinuous across non-smooth segments.

max_profile_length

float max_profile_length = 0.0f

Split the profile curve into shorter segments for UV generation such that no segment exceeds this length.

If the value is non-positive, no splitting will be performed.
