Suggestion: add color ramp options #315

Open frasercl opened 3 weeks ago

frasercl commented 3 weeks ago

Use Case

As a user, I want to pick a (potentially preset) color gradient for a channel transfer function without manually colorizing control points in "advanced" mode.

Solution

This is the one idea in Dan's transfer function editor idea issue #131 not included in the redone transfer function editor work in #294.

Potentially add a dropdown to basic mode with some preset gradients?

Alternatives

Decide not to do this? Add the ability to color pick on basic mode min/max sliders, as a user currently can on advanced mode control points?

Just in case there is something to be learned (maybe not), also see https://github.com/allen-cell-animated/agave/issues/207 and the work in progress PR: https://github.com/allen-cell-animated/agave/pull/155
