WVR_ShowProjectedPassthrough¶
-
WVR_EXPORT WVR_Result WVR_ShowProjectedPassthrough(bool show) Function to show or hide the projected passthrough.
This function must be called after calling WVR_RenderInit().
- Version
- API Level 7
- Note
- Supported from Runtime version 7 or higher (certain devices only). Calling this API on render thread is not recommended due to IPC with Passthrough service.
- Parameters
show: Show or hide the projected passthrough. The system passthrough(surrounding or out-of-boundary) would be disabled if the param show is true.
- Return Value
WVR_SUCCESS: The setting is valid.WVR_Error_RuntimeVersionNotSupport: This feature is supported from Runtime version 7 or higher.WVR_Error_FeatureNotSupport: This feature is not supported on this device.
How to use¶
The following example shows the projected passthrough by pressing button A, and would follow the right controller:
#include <wvr/wvr_system.h>
void pollEvent() {
if (event.common.type == WVR_EventType_ButtonUnpressed) {
if (event.input.inputId == WVR_InputId_Alias1_A) {
float size = 0.125f;
std::vector<float> vertex = { -size, -size, 0.0f,
size, -size, 0.0f,
size, size, 0.0f,
-size, size, 0.0f };
std::vector<uint32_t> indices = { 0, 1, 2, 0, 2, 3 };
WVR_SetProjectedPassthroughMesh(&vertex[0], vertex.size(), &indices[0], indices.size());
float alpha = 1.0f;
WVR_SetProjectedPassthroughAlpha(alpha);
WVR_ShowProjectedPassthrough(true);
}
}
}
void renderFrame() {
for (int nDevice = 0; nDevice < WVR_DEVICE_COUNT_LEVEL_1; ++nDevice) {
if (mVRDevicePairs[nDevice].type == WVR_DeviceType_Controller_Right && mVRDevicePairs[nDevice].pose.isValidPose) {
WVR_Pose_t pose;
q_type quat;
Matrix4 mat = mDevicePoseArray[nDevice];
mat.ToQuat(quat);
pose.rotation.w = quat[Q_W];
pose.rotation.x = quat[Q_X];
pose.rotation.y = quat[Q_Y];
pose.rotation.z = quat[Q_Z];
pose.position.v[0] = mat[12];
pose.position.v[1] = mat[13];
pose.position.v[2] = mat[14];
WVR_SetProjectedPassthroughPose(&pose);
break;
}
}
}
