Currently, all fonts in the scene are parsed and loaded when the scene is initially loaded. And there is a blocking effect because *all* fonts must be loaded before any...
A shader define to indicate which "environment"/implementation the shader is executing on. See https://github.com/tangrams/tangram-es/issues/2153 and https://github.com/tangrams/tangram-es/issues/2154.
OK a couple years later I'm returning to this override issue #576. Here's my latest attempt... This introduces a `freeze` keyword to `draw` groups. When a draw group contains the...
As far as I can tell, the quadkey tile scheme doesn't have a z0. The first quadkey tiles are at z1, and are `0`, `1`, `2`, and `3`. There's no...
@zerebubuth reports the following error (and weird map colors): `[.Offscreen-For-WebGL-0x55c8851728f0]GL ERROR :GL_INVALID_OPERATION : glReadPixels` on Chromium Version 60.0.3112.78 (Developer Build) Built on Ubuntu , running on Ubuntu 16.04 (64-bit) ...
See #455. When buffered tiles are rendered with an alpha blending mode, the overlapping buffers between tiles causes undesirable artifacts ("banding" where buffers are stacked up, where only one is...
In some cases, the calling application may want to provide its own data at run-time. We already have the [`setDataSource()`](https://mapzen.com/documentation/tangram/Javascript-API/#setdatasource_string_-name-_object_-config) method for adding non-tiled data sources at run-time. However, this...
It would be useful to be able to visualize tile boundaries consistently. We often use the `tile_edges: true` flag for this when drawing land or water layers, but this both...
We currently support the return of some feature information via our `interactive` draw parameter and feature picking events (and `getFeatureAtPixel()` method). For a design environment like Tangram Play, it would...
The `amount` parameter for material normal maps is parsed and set as a uniform (`normalAmount`), but it is not actually applied in the shader (`material.glsl`). We can either fix this...
