fix(entwine): change transparency settings #2327

ftoromanoff · 2024-05-13T15:45:11Z

Fix for issue #2323.

This issue point out a bug with the rendering of point cloud where points should be rendered with differentes values of opacity.

Do you think it will fix this issue (#2323) ?

Do you think it will fix this issue (#2323) ?

Currently, I only have look up for a fix for PointCloudLayer (entwine Potree Layers). I will try to continue toward 3DTilesLayer

Understood. Thank you for your answer 👍

Thank you @ftoromanoff for this MR !
Looks like it solves the transparency issue 👍
It also exposed the fact that the 3dtiles is a PointCloud (or contains points) with hasPnts. I like this idea.
Looks good to me !

I have an interrogation, it's not really related to this MR but it's about PointsMaterial.js

WHat's the point of having a DEFAULT object in the ClassificationScheme & in the DiscreteScheme ?
Couldn't we put the DiscreteScheme directly in the ClassificationScheme ? We could access it with
ClassificationScheme.DISCRETE

export const ClassificationScheme = {

WDYT ?

The discrete cheme is indeed a scheme for point classification. But ClassificationScheme is for the 'classification' point classification. That's the reason why there is 2 differentes schemes, One for the classification using point classification and an other one for all the other (return number, type of return etc...). We can imagine that in a future (or a user) want to have different discrete scheme: one for the type of return and another one for the point source ID.

@AnthonyGlt Can you start a review, and validate it if you have no remarks on the code ?
