Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

1. The texture target needs to be GLES20.GL_TEXTURE_EXTERNAL_OES instead of GL_TEXTURE_2D, e.g. in the glBindTexture calls and glTexParameteri calls.

2. In the fragment shader define a requirement to use the extension:
#extension GL_OES_EGL_image_external : require

3. For the texture sampler used in the fragment shader, use samplerExternalOES instead of sampler2D.

Everything below here is all in the C code, no more Java.

4. In the C code, use glEGLImageTargetTexture2DOES(GL_TEXTURE_EXTERNAL_OES, eglImage) to specify where the data is, instead of using glTexImage2D family of functions.

Data Flow in the OSVR Core

Ryan A. Pavlik, PhD (Sensics, Inc) - 29 March 2015

Introduction

The OSVR Core, and in particular the server, has among its primary concerns the management of device and analysis plugins, the maintenance of configuration and the semantic path tree, and the routing of input and output data. It conceptually uses a client-server model, though there is almost always a local (same machine) server, and the design does not require process separation. However, for simplicity, the following is written with separate client/server processes.

In important ways, analysis and hardware device plugins are similar, in that both can produce data that a client or an analysis plugin may request. Thus, both types are considered "logical devices", and "device" refers to this general characterization unless indicated otherwise.
