API to draw points on top of VTS earth environment

[shrikant-panchal]

The APIs to draw line, circle or image are exposed and available for use.
Do we have any API for drawing a point? If No, is there any example available that demonstrates how to draw points?

Any help would be appreciated!

There is no API for drawing point. But you can use renderer.drawImage to draw points. Small image is almost as good as point. In case you need to draw many points like point cloud, you can modify rendere.drawMesh function to support points as rendering primitive:

Just add option to this function:

vts-browser-js/src/core/renderer/interface.js

Line 162 in a0d80a5

RendererInterface.prototype.drawMesh = function(options) {

Pass that option into this function:

vts-browser-js/src/core/renderer/gpu/mesh.js

Line 107 in a0d80a5

GpuMesh.prototype.draw = function(program, attrVertex, attrUV, attrUV2, attrBarycenteric, skipDraw) {

and replace gl.TRIANGLES with gl.POINTS

You can do it using renderer.drawLineString() and passing an array with a single point in it.
